I've integrated Braintree for monthly recurring subscription services and for digital product purchases. For my own purposes, I built my own cart in Rails as I needed a degree of flexibility in check-out. So far I haven't run into any problems. The only thing I really needed was to customize customer e-mails, so I used Braintree's webhooks to my server to send out my own e-mails. Support wise, I was on the phone with them quite a bit in the beginning, and they were nice and knowledgeable. I used them pre-paypal and post-paypal i haven't noticed any differences. Fraud wise, my customers tend to be reliable ones so I haven't had to worry about fraud yet.
