What Payment Provider do you use ?

Hello,
For our new startup PayRequest.io I`m doing some market research, to get a better view on what payment providers business and websites are using, we already support Stripe & Mollie but hope to get more views/options on which PSP to integrate in our system.
Do yo use any other payment provider? And if so where are you from?
Thank you already!
