I missed out completely on the PS4/One era mainly due to arcade games and then having a gaming PC. Decided to strip back and got rid of the gaming PC as found I was always in the office messing about with it rather than with the family, so...
I own a Switch and initially picked up a PS5 and promptly sold it about 2 months after.
Picked up an S and loved it. Upgraded to a Series X and just got the Halo console from MS last week. Also picked up a PS5 (again) from Very at a similar time.
I now use my Series X as my go to console for day to day play, mainly as anything multi platform is usually infinitely cheaper on Xbox. I must confess to preferring the exclusives on PS5; I platinumed Miles Morales and will do the same with Rift Apart. I'm also enjoying the PS4 exclusives I never played. Series X is great for the back catalogue of 360 titles I owned digitally and Game Pass is insane value.
Luckily I don't have to choose as there are pros and cons to both. I find the Series UI's cluttered compared to the PS5. I also find Quick Resume hit and miss especially with RDR2. Also the PS5 controller is infinitely better.
I think the Series X has a better design and a better overall library of games and Game Pass is a game changer (pardon the pun). I also think it's quieter and the back compat aspect is excellent. I also think having Dolby Vision and support Atmos is a smart move....just add it to the UHD Blu-ray movie side of things!
Owning and using both I don't think there is a clear winner. I probably use my PS5 less, but when I do play it I tend to get far more involved with the games I do play. Arguably though this is because I find Game Pass encourages a less focused experience in terms of finishing or playing just one game.
What is interesting is as a huge Nintendo fan boy I've all but given up on the Switch and just gone back to Super Famicom. The lack of 4K on the Switch was never a bother until I owned an OLED and the two newest consoles, now comparatively the Switch looks awful. It also lacks a feature set compared to the other two and running an Atmos home theatre system, the Switch also brings nothing sonically to the mix. As such, my once much-loved loved Switch just sits gathering dust until the other half wants to play New Horizons. I also think other than a handful of titles (and again, I am - in my heart - a die hard Nintendo fan) the Switch has little of interest when compared to the two newbies. I'm hoping Nintendo's next console will win me back.
