I'm in the same boat you are. I'm considering alternatives to Lastpass, mostly because the client has gotten worse over the past few years (since they were picked up by LogMeIn). I don't mind price hikes, but I don't feel as if I've gotten a commensurate increase in the utility or smoothness of the application (though I've certainly noticed an uptick in bugs).

My big thing is the integration of the Yubikey, which is almost mandatory. Bitwarden has this, but their recent security assessment had a showstopper, as far as I'm, concerned:

'BWN-01-010 – Changing the master password does not change encryption keys'

If Bitwarden gets that fixed, I'd jump ship instantly. Otherwise, I may play with Firefox Lockbox and see where that gets me.
