Fanboys don't give (Actual) reasons to own a console. That's why they are fanboys. They speak on knowledge they no nothing about aside from trying to convince others based off brand loyalty. Gabe is a neutral customer to both brands and probably could care less out of either of them however this question is more to do with if he had to choose..
His sole focus is PC gaming.
Well Gabe gives no reason at all. Hes obviously not neutral. He hated the PS3 as well at first. Im sure he will come out at a PS5 event looking like a hostage again after a few years when he need Sony to sell his products though.
