Amazon 4K43N400A vs Sony X900F

First of all, let me say that I rated the Alexa and Smart Features in the middle just because I don't use them -- at least not yet. So don't judge the product based on that!

Similar to the X930E which uses the same X1 Extreme processor, the input lag is low at 4K, for example when gaming with the Xbox One X or PS4 Pro. The...

On day 2 I was unable to get the TV to respond to the remote to turn on. I used the physical power button in the bottom middle of the TV to start it manually and the remote functioned fine after that. Since that, the remote has functioned flawlessly to turn on the TV. I have no idea what caused the initial issue

The install pamphlet was of no help either. Google provided the answer: The Home button displays many things and if you scroll down, well past the bottom of the screen, you eventually find the setup menu. That had all the normal options like channel scanning and input labeling that you expect from a modern TV. Another problem: Sony has placed the IR remote control sensor in the center of the bottom frame of the TV

This TV (I know, it is a FireTV) is very app/streaming centric, but once I found the setting to default to last input, and that is 99% of the time HDMI1, then it behaves like I want, turn on and display my input, not the apps home screen where I have to use the TVs remote to clear it and show input in HDMI1. I mainly use the remote for my satellite service, and rarely use the TV one, but since it is also the streaming apps, I will use it, and it adds yet another Alexa mic to do things from, TV related or not. TV can be slow sometimes to turn on (it turns on reasonably, but doesn't show what is on the input for a while), again thought the remote was misbehaving again, it was just taking time to show anything. Sound is better than old TV, none of them are real great, I do have a sound bar but I can use this TV with out for watching news and normal shows (not action movies or things with lots of audio like music)

At this point I have all my inputs setup, learned all my OTA tv channels, tested Netflix but have not installed Prime, Plex or Kodi yet. I had a Fire Tv cube that I was going to plug in here but it looks like that would be redundant (have not tested alexa commands to this tv yet, or ok google). I will update after I load software the way I want. I was pleased that there was an optical out for my SS receiver, although mostly I am using the tv speakers (sound quality was another big point for me)

I will say that the FireTv interface is very spammy. There's a few sponsored banners on the home page. A lot of the recommendations are for Prime Video -- which I have -- but a lot of them aren't free with Prime. They're recommending me content that I have to buy /rent -- which makes it feel like I'm being advertised to

However, the Android TV OS is terrible and makes me wish I never bought the TV. I read the warnings in the reviews but ignored them and regret it a lot. The interface is slow, clunky, and not intuitive. The voice assistant on the remote is so slow I can’t tell when it’s actually listening
