There are the japanese JCB cards but those are nor accepted everywhere throughout Europe.
I dont think there is a traditional credit card company in Europe comparable to Visa or Mastercard, if I'm not mistaken.
But keep in mind that a lot of payment processors nowadays dont need to be credit cards. Lots of debit cards have the traditional credit card function, and lots of payment systems like Revolut or Klarna have similar functions.
So it probably helps you to know what your use case is: buying stuff online? Buying lots of stuff on credit without actually having the money for it? Buying offline at a POS? Or something else?
