CCBill does have a HUGE negative database, there is no question; but that's also a major reason why they are still in business, compared to the massive number of companies who have come and gone.

What I would do in your case is analyze your form hits / form submissions with both processors and if the approval rate is that far off, on similar behaviour (hits/submissions), present that to CCBill and try to work out what adjustments can be made to your fraud profile.
