- This is the second serious security incident with them. Nobody's immune to bugs, but I haven't seen a similar history with AgileBits.
- LastPass has, IMHO, terrible UI/UX. Things don't work consistently, there are weird, unexpected pauses that look like malfunctions until something visible happens; it took me a comparatively long time to figure out how to map common actions to the gestures that perform them; and finally, this is way down the priority list, but I find it generally kind of ugly. I suspect some of these complaints are partially linked to the next point.
- Lastpass is more trouble than it is worth in Safari/Mac.
I've used 1Password personally since 2008-ish, and think I've had exactly one nontrivial problem with it in that time, which was my fault. (There was some upgrade-path weirdness with the iOS version several years ago, and I left a device unused long enough that it ended up with orphaned data I couldn't sync. I forget the details of what exactly happened.)
1Password Teams didn't exist when my company started using Lastpass, but I'm hoping to get switching onto the low-priority project list.
