I'm familiar with both. A bit more with the Jojo dvd.
I think either way, you should get a teacher who understands all these things and work on it with him. Jojo doesn't stay long on the beginner stuff so depending on where you're at with your hand technique, you might feel lost quite fast. Bill's book starts a bit easier I find and has much more exercises in it whereas Jojo explains more how to it a drum with a lot of different possibilities.
I would definitely recommend that you get both books. And a teacher. I do the Skype lessons if you're ever interested.
