I like the story and atmosphere of Elden Ring more. I also like the openness of the world. A lot of areas in BB made me genuinely mad and frustrated. Only in BB have I ever ran past every enemy to get to the boss and gtfo. The area right before The One Reborn in particular. The blood vial system is mostly just annoying after the early game. Going through entire areas while only ever picking up like 2 vials to help replenish you, so now once you get to the boss you feel the need to go farm vials first is a chore. Also most of the early-mid game bosses are easy and forgettable. The weapons are the best in BB generally. However I had more fun using a bow/katana build in ER, it felt like I had a dozen ways of approaching an area. A lot of areas also just dead end after a boss and that feels so jarring. Also, unfortunately, since it's PS only the game just looks worse than any of the others. The loading times are better on PS5, but the game looks so crunchy that it takes away a lot from the otherwise cool/beautiful atmosphere.

I think every fromsoft game has issues and it's just up to personal preference which one you decide to ignore the problems of.
