[Closed] Which smart tv platform is best?

A dumb TV and some form of box. HDMI-CEC does away with the need for multiple remotes.

Chromecast/Firestick/Roku

Don't choose a TV based on a misconception about remotes!
You probably wouldn't need an extra remote to choose a TV on its merits as a TV and add a proper device for whatever "smart" things you're trying to do. HDMI-CEC allows your TV to pass through commands from its own remote (not a universal one, no configuration necessary, it just works).
So if that was really your reason, you should reconsider.
If you aren't bothered about surround sound pass through, the answer is probably: whatever TV has the best picture (or whatever else you care about) coupled with an Nvidia Shield TV (which will operate just like integrated smart apps in terms of your remote control). It does depends what "smart" things you have in mind though. Whatever HDMI-CEC compliant does them best, plus a good TV. If you are only talking about iplayer and youtube, even simpler solutions would be cheaper. If you have some particular ambition, find a device which does it well (but it won't be a smart TV!)
If you do want surround sound passed through, I still haven't worked the answer.

The LG does a good job, but it depends on what you are trying to achieve, on ours we usually just turn it on and use the controller for BT TV, but then we also have an Apple TV and blue ray connected which all need remotes. For the online apps we tend to use the BT TV box rather than the TV so you end up with multiple internet connected boxes that all mainly give you access to the same things.

Samsung smart tv here, but much prefer the amazon fire stick for the smart stuff.

My new LG is really easy to use. Just as good as using the fire sticks we used before. Actually having it all on the same remote is better. It even has Netflix and amazon tv buttons on the remote to make things easier.

I've just bought a tv for the kids to watch, needed Netflix and Amazon as that's what they like. Not all tv's will allow Amazon to be installed for some reason but LG and hisense do both. So based on it not having to be a fantastic quality telly (As they wouldn't know any different) i got the hisense. What i liked best was the fact the remote has its own buttons for netflix, amazon and you tube so they can easily change between them. Picture quality is not bad either and sound seems ok. The main tv goes through an av receiver so I'm usually not too bothered about that.

The Samsung one is OK; I believe it’s build on Tizen which is their smartphone OS.

There was a bit of an issue with the iPlayer app breaking because it hadn’t been updated, but that seems to have sorted itself over the last eight months.

Gone for the Samsung, it’s only a 32” in a small spot so really not wanting any extra gubbins.

Android tv is great. Sony make them, possibly some others.

Only in the bigger more expensive models. Don’t have room for a big tv.

The way I tested this was to go into John Lewis and tell the salesbod that I would buy the 42in TV that was usable fastest from completely off.

Turn out to be a Panasonic running the Firefox OS. But it turns out they don’t put that on new TVs any more. I’d still recommend my test method though.

As it is now, I just use Amazon FireTv units for smart features and the screens are dumb.

LG is definitely the best of the current crop. WebOS based so fast, efficient and well layed out.

Interesting to see positive comments about Android TV as I've barely seen a good word about it.

LG is pretty good but the updated Samsung one is rather nice.

Samsung seems good. Took about 5mins to sign into everything and get up and running.

I really like LG's WebOS (and I'm not even on the latest version), Samsung's was pretty poor (completely took over the screen) but that was a few years ago and apparently it's much better now. Not very helpful I guess :p I still need 3 remotes though (TV one for the apps like Netflix, Sky Q one and a sound bar one which I need to manually switch between optical and HDMI on as the sound bar doesn't have HDMI-ARC)

If you want a single remote the get a Logitech Harmony

I have both Samsung and LG both are good but i would pick the LG first as it's just easier and faster to use.

I’d echo what Windyg says. We have both although a few years old but the LG is so much better to use.

We went for LG too a few months ago. Mostly based on the fact that it had the Amazon prime app where most didn't and I didn't want to keep using the Firestick as we continously lose that damn tiny black remote!
It does everything we need and works pretty fast.
The only issues I have are:
- no ability to pause live TV and the recording set up (with USB stick) is pretty clumsy and unreliable.
- it seems to keep losing channels everytime there's a signal issue so seem to be returning it every couple of weeks to get them back.

I actually did some research for once and chose LG for the WebOS, it seems okay, I'm told you can run Virgin media through it, but I haven't cared to look yet.

It also has a NowTV app which we use a lot, so happy with that, no Red Bull TV app though sadly, I'll need to work something out for that come WC season.

I think on top of the OS you need reasonable hardware to run it, details seem very vague, but they seem to use smartphone/tablet hardware which seems an obvious choice, again not much in the way of detail available but some are single core based and some are quad core.

I really am a novice with SmartTVs, but WebOS lets me add a external hard drive to record live TV, haven't tried yet but also I can download media in pretty much any format from my Laptop, plug in the hdd and it'll play through the TV, watch Star Wars 4K77 at the weekend, which was cool. 4K file are MASSIVE! I suspect I could make it more efficient using a NAS, but I don't have one at home and cables are already a disaster behind my TV.

We got a new LG telly with WebOS. I'm rather pleased with it. Do not underestimated how nice it is to have dedicated netflix and amazon buttons on the remote.

The interface etc is also super fast.

From memory we payed about 600quid for the 49in size.

I have a slightly older Sony which can be a little flakey in the smarts.
Sometimes apps wont run unless you refresh internet content.
It doesnt have most of the latest apps and Sony dont add them from their servers which is a pain, so I have no ITV Hub or BTSport.
So I generally use my chromecast and phone control instead which does work pretty well.

I wanted to ditch multiple remotes a few years ago so I bought a high end 4K Sony with android, it is a 2015 model. It was incredibly unreliable at the start but after multiple updates and patches it is now very stable. I’ve grown to like it as it does everything with one remote, but now looks like Sony have dropped the 15 models from future android updates already!

Samsung here with Samsung home theatre. The tv comes with a bluetooth remote which controls channels, volume, apps. Nice simple and minimalist setup.

Gone for the Samsung

Under no circumstance is that is ever the correct decision. Ever.

The correct answer was LG as per all the responses which you ignored.
