Resident Evil 4 is an extremely comfortable game that I can fire up and play whenever. Even after completing it twice, RE2r is a very stressful game that I don't think I would come back to readily. It's clearly a more effective horror title but I don't think it would take my top spot.
RE7 was quite scary, but also sort of uninteresting and I didn't finish it. The slow gameplay and first person perspective didn't feel like what I wanted.
RE6 is totally awful.
RE5 is decent but some steps back from 4 in certain ways and the coop focus makes it worse for me.
RE3, RE2, RE1 (+ RE1r), CV and RE0 are all in the camp of old resident evil's I've never played to completion. I did get a few hours into RE1r, briefly played RE0, and played a few hours of RE:DS, but the old style of gameplay never felt good to me and I struggled to make progress in the games. I would generally get stuck on something progression wise, then just never go back to the game. I intend to play at least a few to completion even if that requires the use of a guide at some point, but haven't done that yet.
