For automotive use, I would agree that floor jacks are quicker, better, and more safe.
For heavy trucks, I like the hell out of the shops 22 ton bottle jack. It's similar to a floor jack. It has two 6" rubber wheels and a three position handle that can be locked. It can be raised like a floor jack by pumping the handle or with compressed air. It's quite a bit more stable than a regular bottle jack because it's base is about a foot square. The only way to fly in a truck shop.
The only other type of jack I'd like to have at work would be a frame jack.
