I started with LastPass, but switched to OnePassword when LP was acquired by LogMeIn. OnePassword (the standalone client) was great, but it didn't work with linux at the time.

I ended up trying keepassxc for a time, but ultimately ended up with bitwarden, which has served me extremely well.

BitWarden isn't as polished as OnePassword, but its not far off. Since its purely browser-based, it works with every OS.

It isn't awesome, but the best all around one I have seen is LastPass.
