3) Better interface and api
4) Prechecked Crosssales with others that have merchant accounts
5) You have your credit card #'s
6) Cross-sales, you can set them up yourself and change pricing etc on the fly
7) Ability to bill any amount, and any # of transactions (Webcams) or Upgrades without the user having to re-enter their card.

I'm sure I could list more.

I personally think CCbill is a great solution and should also be used, never put all your eggs in one basket.
