In terms of picture quality, it's one of the best but the Android TV experience sucks in comparison to my NVIDIA Shield (not a TV, just an external box). The Shield is much smoother/responsive, fantastic with updates and just generally a far superior experience.
If Sony can be better with updates and make the experience smoother, get rid of their excessive bloatware and not have such a laggy input from the remote, they'd win hands down, but otherwise, NVIDIA is the king and have been for a long while.
For reference, I have the original NVIDIA Shield TV from 2015 (currently Android TV OS 9) compared to my Sony Bravia ATV3 from 2018 (currently Android TV OS 8).
Hisense h9g is getting very good reviews. There is also TCL Android TV that is getting better reviews than Sony.
I have Sony old and new. The older ones are a bit more clunky in the Android TV UI. I don't know why people complain though. The amount of time I spend in the Android TV U.I. is very small compared to watching content.
The more expensive Sony's have hands free assistant, also called farfield. I recommend it , even though it has a bug, after sleep doesn't work until you play with remote. Hopefully that gets fixed with an update. Hisense and TCL also have farfield. You can do things like ask the time, weather, turn on lights, etc... Functionality is only increasing.
Yes the Sony X900H specifically is the most powerful Smart TV on the market vs anything else. Sony has gone "all in Android TV" with their 2020 models with snappy, even powerful chipsets now under the hood.
All the building blocks (Firmware, Google Project Treble complaince) are there now for much easier long term support. And that is what you are paying a bit extra for - support (& picture quality). Which will be better vs any other Android TV brand out there. That is really important long term.
Ignore all you have read about previous underpowered chipset Sony's that a whole bunch of people have complained about here a LOT. Those TV's are no longer relevant to the 2020 Models discussion.
The 2020 Sony "H" models from the X800H upwards are great to really good (X900H) these days with snappy RealTek or MediaTek chipsets under the hood for Android TV and Apps usage.
And the reasons why are outlined here:

You have to be REALLY careful about which Model Sony you buy. It's extremely important you get one with a MediaTek MT5893 (2019 X850G, X950G, A9G or 2020 X950H upwards) or MT 5895 (X900H) under the hood for snappy Android TV usage.
Be very careful choosing.
My Sony BRAVIA 800G XBR65X800G has a decent picture, and decent sound, but the Android TV function is disappointing as it is slow and very "clunky" compared to a simple Roku Streaming Stick 3800R that I have attached to it. 99% of the time, we use the Roku, because it is so much faster and smoother to use.
Another ongoing issue is that the TV will randomly disconnect itself from our home WiFi, which requires a hard reset to correct. No other devices in the house have this WiFi problem, so it's definitely a TV issue, especially since it immediately reconnects after a hard reset.
Finally, we find the TV itself will often be completely powered off for no reason vs simply being in standby mode, and when we want to use it, the whole TV has to restart when we turn it on, which takes about a minute or so. The power issue didn't happen when the TV was newer. It's not yet a year old, so I'll be contacting Sony for a warranty claim.
Overall, my Sony BRAVIA 800G XBR65X800G TV has been a disappointment.
Philips has much better Android OS implementation.
I do. I have it and it's KD-49XF7596. Very good.
I bought the X900h almost a month ago, replacing my 2015 Bravia. I swear a great picture, maybe not OLED quality, but I couldn't afford that one. Watched my first HDR 4K stream from Vudu, and "Annihilation" never looked better (including cinema).
But, you're paying to the X1 processor (sweet), and the longevity you get with Sony. Never need to buy an extended warranty for a Sony.
Bought a sony with built in android for my parents instead of screwing about with inputs for firesticks etc. Really looked in to it then made the purchase. Turns out even when you add a hdd to it u cant rewind live tv unless its recording that Chanel. Had i known this i wouldnt have bought it. No where did i see that this was not possible. Considering any shitty pvr can accomplish this. Total deal breaker. Buy a shield.
It depends what you want to use it for. If its for Netflix, Amazon Prime, Hulu and any other streaming app then its great. I'm sure it will also be ok for simple games. But if you are looking for playing those process heavy games then look somewhere else. I enjoy retro games using Mame4Droid ;)
Just get any TV and buy a Shield TV
