Braintree is awesome and their customer support is stellar. I don't work for Braintree, but I've used their production API in an extensive project where Stripe basically told me to go fuck myself because of this so-called jurisdiction.
I was integrating Braintree a year ago when some of the documentation was unclear. They're technical support was amazing on the phone, and cleared anything the documentation was lacking up.
Also, talking to them wasn't like talking to a tool. Didn't feel like a megacompany, but just another person on the other side of the line.
