After using both 1pass and LP for a week, they are both equally clunky in their own special ways. LP really did bone it by not enforcing super strong master passwords AND not encrypting metadata. 1P secret key is clever, I didn't understand it clearly until recently.
Other than that, the UX/UI is essentially identical: same UI warts and bugs, same frustrating behavior, same bloat, etc. Both are equally fucking annoying with getting popups and fill-in fields wrong 25% of the time.
N.B. I have not used them in a corporate setting where you may need to manage & rotate credentials, though.
But based on metadata and lack of forcing users to create strong passwords, 1P has the right to point at LP and laugh in this case.
