I agree that the bitwarden UI isn't very good on the desktop app and in the browser extension. I don't even use the desktop app at all anymore. One positive for protonpass is that the ui is looking pretty streamlined and it feels fast. I think for just the endless regular internet accounts either is fine.
It's a fair point about small vs. big. I mean security by obscurity doesn't really seem like a strong point for small, but who knows. I think higher value targets will always end up using the bigger ones anyway.
Important stuff (banking/development secrets) maybe use something like gpg based and offline like https://wiki.archlinux.org/title/Pass or the Qt frontend https://qtpass.org/.
