Braintree is now essentially paypal, so that is off the list. Adyen is good but can be strict with what businesses they support.

In short, i recommend using local providers, not these multinationals. Each country has a bunch of them, so there is plenty of choices, they are just not world renown brands.

What about the old school processors like Authorize.net and Cybersource? It has been over a decade since I worked with them, so not sure what they are like now.
