What should i play on?

Hey people of reddit, 5 months ago i lost my ps5 because my mom sold it and not gonna' lie these 5 months have been awful to me.

This month I received the great news that I'm getting my first job, doesn't pay much but it's better then not having any job, but the question is I have had my Playstation account since the start of the ps4 launch, have hundreds of games in it, but I still want to play other exclusives like Halo and Gears of War, and I don't have a trustable source on what gaming console or even PC should I buy.

Should I buy a ps5 to get all my games and account back?

Should I buy a Xbox and try their catalogue and exclusives?

Should I buy a PC and explore?

Please let me know, it'll take months to get the money I need for one of these for now, still have a lot of time to think, but I would like your guy's opinions.
