The PS5 is just a PS4 with new design and a bit better performance. No Exclusives because the developers know, that on pc they can just plug in a controller and have the same feeling ( And even on a handheld, aka Steamdeck... ). My recommendation:

A handheld PC ( SteamDeck ( my favourite ) or the ROG Ally )

Differences:

Steamdeck: 2 Trackpads are really great! You can easily work with games that are mouse heavy. ( I use it for shooter games ) Fully customizable buttons ( literally everything, with even sub menus, alternative modes, community layouts etc... ) Joysticks are on the same height. Linux, less overhead and longer gaming sessions. ( You can tinker more on linux than on windows, but valve did a great job on not locking you in so you can easily install any OS that runs steam ;D ) Repairability is the best! ( Valve has a cooperation with IFixit with replacement parts ) Upgradeability is easy ( For example bigger storage, better thumbsticks ) They hear to the community of gamers and repairers. Pausing games is so easy ( Just press the power button and it saves the game where it is and saves power ) Its back again in under 5 seconds.

( Just to note those "Gamepass" Games can be easily installed if you just install windows on the steam deck if you want it )

ROG Ally: No trackpad ( so only controller optimized games ) Windows ( A lot of overhead but best compatibility with games. ) ROGs software is sometimes a bit clunky but usable. Joysticks are not on the same height. You can plug a external GPU with a proprietary plug. ( Literally a GPU in a box with some extra costs, but it improves performance on some gpu intensive games )
