My problem with passwordstore is that it's just not convenient to add passwords (via browser).
With Bitwarden or KeepassXC the extension offers to store the login data when I sign up or use one login for a first time.
With pass i have to do it manually which isn't hard or does take long, but it's still additional work.
I ended up using KeepassXc with keepmenu[0] as a script for roffi/demnu
