Which game should I play?

Hey guys! Thanks to some fall and winter steam sales I was able to buy Darksouls 1,2,3 and Sekiro. I also recently bought Bloodborne. I’ve beat DS1 last night and the plan is to beat them all but I’m having a tough time choosing which one to do next. So I figured who else could help non other then the souls community!

For some extra context: Aside from DS1. Ive only gotten up to the cleric beast in Bloodborne. It’s been a lot of fun too but I kinda want to save the rest of the game for last / use it as pallet cleanser for when I’m needing a break from a different souls game. I was thinking to do 2 - 3 - Sekiro - Bloodborne but My roommate thinks I should do Sekiro first before anything else. He says I should learn to parry already (on top nothing’s love for the game). To which he has a point and I am kinda leaning that way.
