I've not used LastPass, but I chose 1Password because it has the ability to sync with my iOS device over wi-fi. So I don't need to store anything in the cloud, but still get syncing between devices.
It also has options for using DropBox or iCloud, so if you do sync in the cloud, it's still your own account on a different service. So there's not a single point-of-attack like there apparently is with LastPass.
