Stripe/Braintree are a lot better than PayPal. PayPal will never take your processing history into consideration if their algorithms decide that your account is connected to some account with past violations. This happened when my developer used his API keys on our production resulting in our account with 1M+ revenue/2 years (very few chargebacks if any) of operation banned. As a small startup, it was a death sentence for our business, finding another processor at high volume is difficult when you've no history to show!
