Right now I'm using Paypal, and I can't wait to move to something else. It seems Pintpay's fees (3.9% + 30¢) are comparable to Paypal (non-Pro), but I'm fine with that premium as long as it's a better experience than Paypal. I want a nice clean interface that doesn't take 60+ seconds to generate reports on my currency subscribers.
As mentioned in another thread, the callback hooks are a must for me to migrate my service (SocialGrapple) to Pintpay, but everything else looks great. I eagerly await!
Edit: Just found this comparison chart of your fees vs others (Recurly, Chargify, Paypal Pro). Very handy: https://pintpay.com/about/compare
