I use them too, and have been extremely happy with the service I've received so far.
I'm based in Australia but sell mostly to overseas customers and bill in USD. They take a 4% cut this way, but don't hit you with a currency conversion fee like PayPal do.
I used to use Stripe, but had an issue where my account was flagged as fraudulent by their ML model for God knows what reason. They sent me a link to click on to provide more information and escalate the issue, but the link went to a 404 page. I forwarded the email to their support but never heard back from them. Tried to call them, no dice. That's when I realised my business was relying on a service which could go down at any moment and didn't provide adequate phone support.
Cancelled the account and signed up with PIN Payments on the spot. The few times I've spoken to them, I've received a response from a real person that actually knew what they were talking about.
Couldn't recommend them more.
Hopefully their influence doesn't spread to the web too.
