Based on the games you mentioned, and your interest in openness, I’d recommend a PC if you can afford it. In the long run, because games can be purchased at lower prices, and there is no subscription for online (like XBox and PS4), the price tends to even out.
I have chased the hardware loop before, I just want to be able to lay in bed and game, because of my dual herniated disk in my lower back I cant sit at a computer for more than 5 minutes before my back hurts and legs go numb.
