I've implemented both in a typical SaaS app.

Braintree first, because it was the only option, and then Stripe because we were eager to get away from Braintree.

In short, Braintree was very painful to implement and run, while Stripe has been both easier to implement and operate.

Even with the sunk-cost of a working Braintree implementation it was an easy choice to switch to Stripe.
