This. I prefer Xbox but buy exclusives on PlayStation. But with most games going everywhere it’s just a matter of preference. One reason I like Xbox is for the controller and I do like the direction they are going in with GamePass. That said I also love PSVR.
Console wars are stupid. Just do you.
For me it mainly depends on version differences. Like I'd go for switch versions for the portability factor and occasionally they come with extra content. But they also more often than not cost more than the ps4 and xbox versions so when the price is 10 or more difference I just picked up those over switch versions. And we have to throw in pc as well which occasionally is the cheapest option for a game.
The only things that matter to me would be price of games, the systems and accessories and whatever exclusives they have (which nintendo usually has the strongest grouping of exclusive wise). I wait till the systems are cheap to pick them all up and play all of them. I see no reason to back only one of them unless you have no interest in what few games other systems offer.
