I've used both extensively and in our mobile apps, we've switched back and forth. Stripe is noticeably easier to implement on mobile (including Apple Pay). Maybe not an order of magnitude easier but close. Part of the reason is that Stripe's documentation is much better.

I'm not saying that's a deal-breaker–and I do think Braintree does have an advantage in some areas–but I'm just attempting to answer your question.

Braintree/PayPal really needs to hire a serious UX/frontend team to clean up their docs and dashboards (monospaced font srsly?).

I think Braintree's document are really nice looking. I really like the look of monospace font at larger font sizes. There is also a ton of designers that use monospace font for more developer related things.

In the spectrum of evaluating the quality of documention, I never would have thought that fontface would be the first mention.
