I switched from keepass to vaultwarden years ago and for my usage I wouldn’t switch back.
I needed to be able to share some passwords with other people. I think the clients are much better. I like having a website available as a backup to access a password. All in one package that works well so I don’t need separate mechanism to synchronize between different installations. I like the easy sharing secrets through links and not having to send in cleartext with emails or texts.
And for selfhosting I like that you only need the server only for syncing newly added secrets - if vaultwarden had to be online always I’d switch back.
