I have no knowledge of what BrainTree does, but if I'm picking a service with an API, I'm picking the one that is easiest to learn (preferably there is little that needs to be learned), I'm not picking one that requires me to switch languages -- or just as bad, locks me into one of a few languages I'm currently using.

BrainTree does payments. They have concerns about security that most apps do not. Who really cares if bugged timeout/retry logic makes your app post twice to facebook? Probably no one. Who cares if bugged timeout/retry logic makes your app bill them twice? Probably everyone.

BrainTree and you may not make the same decision, and you both could be right.
