1Password
Expensive, but there is a free Metro version (in alpha) for WIndows RT / Phone, as well as Windows / Mac / iOS / Android versions. No Linux client but 1Password Anywhere covers that.
Syncs with Dropbox, Onedrive and iCloud, or your own systems if you want to.
Finally - can import LastPass pretty well.
I use both. Ironically I switched my primary vault from 1P to LP last year after I grew tired of forking out for version upgrades, but I am glad I have it in reserve. Old versions beyond 3 still work fine.
Biting the hand that feeds IT
