Much happier with 1Password since we switched from Lastpass. Consistent UI, proper OS integration, multiple separate vaults, not to mention the security story seems better (I've seen several LP vulnerabilities of concern but not yet seen a 1PW one that worried me).
I've been tempted to do away with the extra clicks and just use iCloud Keychain and encrypted Notes, but 1Password feels like less of a black box at this point (maybe just because I've been using it longer). It also seems smarter about filling out forms than the browser-native options in Chrome and Safari — not perfect, but better. I don't use their subscription service, just the desktop and mobile app.
Thinking about it I'm really only using it for convenience, security/strong passwords is in second place.
Given all the problems with OpenSSL, I really wished they used something like BoringSSL.
For basic crypto algorithms, there's little to no difference. Most of the changes in BoringSSL are in higher-level code, like TLS and certificate management.
