Personal anecdote --- Proton Pass very quickly went from worse than Bitwarden to better with more reliable auto-fill.
Doesn’t it cost much more than BW? I don’t really understand if the main complaint is people worrying about losing the free option (which hasn’t even happened)
Not sure it makes sense on its own at $5 a month (currently discounted so $3), but as part of the Proton Ultimate package which gives you mail, VPN etc in addition it's not bad in my view. YMMV.
Worked well for me, I use it for non-critical web accounts and such. KeePass for the few core accounts etc.
