Hmm, I've tried LastPass, Enpass, a handful of Keepass clients I can't remember the name of and (shortly) 1Password, and I can't really find anything Bitwarden does that much worse than any of these. To be perfectly honest, they're all kind of clunky, IMHO.
I feel like I can think of a lot but I'll give you one that, to me, is Bitwarden in a nutshell:
What happens if you open your browser, go to https://news.ycombinator.com/login, and hit Bitwarden's autofill shortcut? Nothing, because you didn't log in to Bitwarden first. Pretty much every other password manager will ask you to log in and then they'll autofill.
