Windows has more drivers for more things, but if Linux has drivers (e.g. you buy a Laptop with Linux support) then driver management is massively easier.
I spent god knows how many hours getting the windows drivers for my last self built gaming PC working. Linux I just installed and was done. In reality the Windows experience was also a lot worse than having to drop to the console occasionally. It definitely required more in depth knowledge, even if everything was UI driven...
I own a steam deck and love it, but please, let’s temper the enthusiasm with realism.
