Let me start off by saying that Bitwarden is free and full-featured, and the premium features cost minimally and sustainably. Nobody is going to beat that, and some of its users aren’t going to leave unless there are security issues.
Bitwarden has been criticized for its UI for a long time (see Wikipedia article). I think the new UI mutes the criticism from the press somewhat, but it still remains an issue.
I personally have some other gripes, but see paragraph 1 above.
The alternatives are well known too, and switching to them is dead easy. Just try them out.
