Yubikeys offer PINs and passwords, a physical user presence button, finger print sensors, NFC, and you can use one key on different PCs, you can deal with PC hardware failures by moving the key and deal with key failures with a backup key, and and it's compatible with Windows, Linux, OS X, Android and iPhone.
So they're a heck of a lot more flexible.
But in a corporate environment, you might not give a shit about Linux support, and you might think it's better if the user can't unplug the key and plug it into another PC, because corporate workers should only connect to corporate systems with their corporate-issued laptops, and corporate helpdesk will sort out any hardware problems.
