I was a big fan of Braintree. It got acquired by Paypal. They cause their users pain quite often since they're a dominant company that doesn't have to care:

That puts Braintree into liability category as Paypal's influence on them increases. Leaves Stripe as safer bet for now if they don't pull stuff like that on customers regularly. If Stripe IPO's, they might turn into villains as well. However, there will be another startup or mid-sized company differentiating on quality of service by then. I'll recommend that one.

Note: If Stripe management is reading, I suggest that they continue to pull less crap than Paypal with better service as a continuing differentiator from this point on. It should always work. Braintree also succeeded that way when competing with payment processors.
