WorldPay is available in New Zealand and integrates with ChargeBee (for subscription billing). This is pretty much the only reason I went with WorldPay.
If you're operating in another country though, you're probably better off going with someone like BrainTree or Stripe, since they'll be heaps cheaper and easier to setup. WorldPay were thorough and professional and their service is reliable... but then you could probably say the same for pretty much any of the payment providers.

The application process took forever (from start to finish, around 4 months). Don't expect to be up and running very quickly with these guys. They'll need documentation supporting the fact that your grandmother had a cat in 1972 and various other details that you might not see the relevance of (OK, maybe not the cat... but you get the idea).
I also didn't much appreciate the fact that I had to pay, just to make an application to become a WorldPay merchant (something in the order of NZ$480)... but that appears to be standard down under. SwipeHQ also charged me NZ$100 to make an application with them... after which they lost the copy of my passport no fewer than 3 times (the 4th time they asked me for it I gave up on them)... so I guess to WorldPay's credit, at least they came through in the end.

PayOS' biggest advantage is its omnichannel capabilities, and it also comes with integrated inventory management. Review collected by and hosted on G2.com.
Sign-up for a merchant account takes longer with PayOS than with competitors. But the extra five minutes is more than worth it when you take into account the flexibility of the platform, and the fact that you can manage all channels from one merchant account.
