I’m not sure what you’re comparing it to. Keepass is free too, in fact it’s open source. In my opinion, local software and database that is under your control is always superior to cloud.
Keepass over Bitwarden offers a lot of plugins and integrations, again, if you want more customization or automation.
But, I would say you can use any online password manager as long as it’s end to end encrypted, so Bitwarden is a good choice.
