is Legion Y700 2022 buggy?

I want to buy Legion Y700 2022 or Samsung s9 FE Tablet. I am worried that the Legion would be buggy or dead after 2 years of using. I want to use the tablet for a long period(4 years).

Additional Info: I like to draw 2D Chibi style and take notes. I also want to play Genshin at 45fps, medium graphic for an hour without overheating.
