I'm really enjoying it so far!
Old Yharnam and the Blood-starved Beast kicked my ass (damn poison). Had to summon a hunter to help with that. (Arthur I think? Alfred) I made it way more difficult for myself because I hadn't started using the other consumables like Beast Pellets or Lures at that point.
I ended up beating Vicar Amelia first try, too, though! I'd started actually looking at the consumables I had and saw I had a bunch of Fire Papers to use, so that fight went really well.
I'm taking my time with it and mostly grinding at the moment.
As for the other games, maybe? From what I've heard Elden Ring seems like it's the most beginner friendly so I might give that a go eventually.
