Been looking at this for a while now. I have an LG B7 55" Oled TV, that is fed from my Sony AVR, and everything plugs into the AVR, 4k Blu Ray player, PS3, Xboxone, Roku Streaming stick plus.
I cut the chord earlier this year so all my content is from Netflix, Amazon Prime, Now TV, Youtube, BBC Iplayer, spotify, Amazon Music and Plex streamed from my Roku and 4K Blu Rays.
I'm needing to replace the Roku, because its on the fritz, i think it got too hot and got fried a little.
Apple TV 4K at this point seems to be the front runner in terms of it will support all the apps I use and handles proper Dolby vision etc. But its pretty expensive, and as in the title, I can't stand the UI of apple devices or apps. But could live with it.
Nvidia shield doesn't support NowTV
Firestick & Roku don't seem to support as many formats?
John Lewis in the UK are doing the Apple TV 4k 64mb for £199 and you get the two year guarantee, and a year of Apple TV.
Any other suggestions I should look at? Or does anyone just use the TV builtin apps?
EDIT: Thanks for all the input. I went out and got the Apple TV this morning. All looks great. But my god it took 90 minutes just to sort out and unlock my old Apple accounts!
Can't really help you but just want to pile on for Apple TV. Whoever thought a damn "touch pad" was ideal for a remote was a god damn moron.
