Currently using Nvidia Shield TV (Tube) in my living room as main streaming device

Thinking of getting Apple TV 4K (2021) to replace it as just changed family member devices to apple ecosystem already.

Wanna know any cons on Apple TV 4k right now from users here ?

Current home living room setup:
LG CX
Samsung Q950T soundbar

Nvidia shield connect to soundbar to get either Dolby Atmos or DTS:X
Only con right now i find is that native Youtube app of Nvidia shield cannot support HDR 

Yea, same, going to be dad soon here, cannot blast my movie session 
Right now i plug direct to the soundbar then output video signal from soundbar to TV.
So far everything works well except:

1) Youtube app under Apple TV cannot do "Match content" so right now my default setting for the UI is set to 4k60 HDR 
2) There is no VIU app for Apple TV (mainly for my wife's K-drama)

Others still under exploration.
