but this whole generation Sony and MS sold us theses consoles as "premium" and it was an exciting thought to think that console players may actually be getting "the best of the best".
Consoles have never been the "premium" experience of video games.
...BUT I would also say that shouldn't be your sole reason for going PC.
My two biggest reasons for sticking to PC as my first platform are flexibility and legacy support. I have a big desktop and a laptop, and I know I can install all my games on either one, or both. If I had more money I'd get a GDP Win too for handheld PC gaming. I know when I buy or build a new, better PC I'll have no problem moving all my games over. I still have PC game discs from the 90's and early 00's I can install today. I know overall I can just do more with my games, which makes me more comfortable buying digital PC games than buying digital console games.
Really, it's just the fact that PC is an open platform that makes it better for me. Power isn't even a deal-breaker for me. I'd be fine with a PC that performed no better than consoles just because of all the other advantages. If PlayStation was an open platform, I'd be fine with that level of power. If I ever reached a point where for some reason I couldn't play AAA games on PC anymore, I'd probably still play stuff like Doom or any number of not-graphics-intensive games on a laptop or something.
Aside from those reasons, there are actually a lot of games I spend a lot of time with that are either PC-only or tend to come out on PC a year or more earlier than consoles, and I think OP should try to find some PC-only games as another reason to get into PC. It's just that those PC-only games don't tend to get the same advertising and promotion as AAA console games. They might just spread through word-of-mouth or pop up out of nowhere on Steam.
My top game right now is Arma and I've been meaning to get back to Disco Elysium which comes to consoles later this year. Umurangi Generation is one of the most interesting games I've played all year. If you just keep peeking at whatever shows up on the PC game storefronts or talk to people who stay on PC you'll run into a lot of great obscure games most people will never hear of. A ton of indie darlings come out on PC first as well. And if you're a retroist then PC is absolutely the best platform.
