Got a high end PC, a PS5 and an XBSX and SS. (and Switch).
Some games are designed around the TV/Surround Sound/Cinematic experience and controller, others are designed around PC, keyboard and mouse etc. Throw on Gamepass Ultimate if picked up through the loopholes to get it stupidly cheap; which then gives you library on PC and XB titles to access; and frankly I've had good reasons to play all of my machines; they've all got great experiences, and some games just play dramatically better on one platform or another; either down to performance, interface etc. Not played it yet but Elden Ring is a perfect example, XBOX and PC have really annoying stutter, I understand for whatever reason, the PS5 version is buttery smooth, but having all consoles and a decent PC, means I have the opportunity to not only play any game that appeals to me, but also to play it in whatever way suits it and me best.
Have an OLED set and AVR surround kit which also helps, need to upgrade the AVR in the next couple of years though as the current one doesn't play nice with VRR etc, but want the kit to mature before I drop money. Having a nicer TV set and surround sound kit definately boosts my enjoyment from the consoles; having said that even the Series S with a weaker set in the bedroom is a much nicer experience than the previous gen, the SSD and increased CPU performance just make general usage much nicer.
PS4 was OK, especially with external SSD and upgraded higher speed and capacity internal drive, but XBOX One just drove me mad with how slow and unresponsive it felt, after being a PC+SSD user since mid 2000s. PS5/Xbox Series are just such a step up in many ways from the old gen it's not funny; I'm not surprised there are a lot of converts. The new consoles (even the Series S for ~£220) also give you a lot of internal hardware for the amount you pay, and couple with gamepass for easy access to lots of games for free, again, I can see how a lot of people are picking them up; whether converting or not.
Yes you pay a premium for console games new, but Gamepass Ultimate, second hand hand and watching for sales etc can take a lot of the edge off, and having all the platforms gives me a hell of a lot of options, especially with so many titles either getting decent sales pricing on PCs and console these days (as pricing in the UK is actually quite competitive compared to some countries); and a distinct number of games giving you free upgrades to Series or PS5 titles for free if you have a previous gen copy.
I'd actually argue the best experience; if you can afford it; is having all the platforms, as they all complement each other these days, and bring something different to the table. Not like last gen, where I was so dissapointed in Xbox One, I ended up selling it off as I didn't use it, and felt very little inclination to do so.
