Best 3rd party paid subscription API?
 

Out of the below options which 3rd party payment method do you like best for automation, ease, and low fees?

I just use Paypal and 2checkout. I want to replace 2checkout for CC transactions as it isn't fully integrated with vBulletin like Paypal is.

Paypal
NOCHEX
Worldpay
Authorize.Net
2Checkout
Moneybookers
CCBill

Thanks,
rob
