Which is a better tablet for animating?

Note: Please do not say "get that one because everyone has one" and vote. I want a good reason.

To be honest, whenever I go to a computer store, graphic tablet sections only show bamboo products.

What in the loving world is a vis tablet..

Even though I use my Genius tablet for animating on my laptop (I mostly animate on my laptop) I do use a Bamboo tablet which is on my computer desk and it's far better than most tablets I've used. Plus I don't know what in the daisy a vis Tablet is... But yeah, most people don't use Bamboo tablets because they're mainstream they use them because they're the kind of the best whether you're on a budget or not.
