You should really base this on preference, they don't come in any order, ultimate has a slightly different story-line than the original, the original is alright but in my opinion quite boring. If you want to see something with interesting characters, good animation, and a good plot then the best choice would be ultimate.

Again all up to you, if you watch ultimate first and are still curious about the original then id watch the original after ultimate. You should also check out the manga it's pretty good.
