For me, I’d have to say PC.
I have been on Xbox since ps3 got hacked and was down for like a month so that’s what 2011-2023.
I moved to PC this year, and I’m impressed.. but it did take some getting used too.
Different game catalogues was confusing at first, you have multiple on Pc but only 1 on Xbox.
Downloading drivers, updating windows etc is sometimes annoying.
The positives out far do the negatives.
More games / better games
Better graphics & ability to edit graphics settings to needs.
Game mods
Customise hardware
I do miss the Xbox Home Screen etc but I use the Xbox app on PC
