If you don’t enjoy gaming now, it might be complicated to figure out why. Usually it comes from other distractions that block you. I enjoy some games so much more on the steam deck. I also recommend to play smaller good games like Inside or Limbo. If you have the spare money, go for it, if money is tight, buy running shoes or go swimming or cycling. And come back to gaming once you feel it.
But to be honest. As a person who is quite curious, I love to learn about these small differences, since it reveals further questions about the manufacturing and implications of the difference. Playing and analyzing the Steamdeck is fun in itself. There is also something similar going on with other devices. Also its nice to have an curious, informed user group.
