I never liked 1pass. I don't like the fact that you have to install a desktop app to use the browser extension. Also the UI is a bit annoying and sometimes it feels like it just gets in my way. The UX for multiple vaults is not so obvious at times and you don't realize you are only searching one vault instead of everything. Copying and sharing between vaults is also annoying.

I really don't see what 1pass does better than LastPass. LP has a bad security reputation but other than that it's much more enjoyable to use
