Most record types (software license, wireless router, documents, drivers licenses, email accounts, membership, passports, maybe more) don’t exist in Bitwarden. I’m not sure what happens with all of those, maybe transformed into secure note, but again with all of the attachments removed. The lack of categories is also a nuisance for organization, you can create folders but have to manage it manually.
I’m still glad I switched, having bought 1Password on a bunch of platforms and a bunch of paid upgrades before it turned into a subscription. It probably would have been less money if it had been a subscription from the start with all the times I bought it. Maybe it’s irrational, I just don’t like being so dependent on a subscription service, and having a local network sync between my devices was just fine. Same reason Lightroom can pound sand with their $120/year licensing, I’m not going to keep my photo library in something that I just have to keep paying for the rest of my life.
Bitwarden is good enough for me, with 1Password as a subscription you can look at it and realize “this is going to be $36/year forever.” If I spent any time in it, might be worth the expense. I’ve bought a lot of software and I don’t mind paying for good software. But I’ve moved the things that were attachments to an encrypted disk image, and 99% of my password manager interaction is via auto fill so I don’t actually care how polished the UI is.
Family sharing would be a more compelling reason to stick with it if you’re using that.
