Admittedly the mobile clients have since been rewritten to be native (they were _really_ slow before), but Keyguard is still much faster/lighter.
I started using 1Password at work and it's just a.. nicer experience? It does all this and more. Everything is fast, the browser extension is more proactive/recognises fields better (Bitwarden can't really do multi step logins), and the desktop client isn't a chore to use.
The best comparison I would give is comparing Immich and Jellyfin (if you've used these), they are miles apart in terms of end user experience/polish/efficient design. One is engineered, the other feels like it's been hacked together by hobbyists.
And it frequently fails to detect login fields, or does detect but fails to fill them with a generic error.
Try to bring it up on bitwarden reddit sub, they will eat you alive
