I like being able to look at providers with different geographic coverage and services without jumping between so many separate websites. It gives me a better starting point when I'm trying to understand what might work for a particular business situation. The search and filtering options are useful too, especially when you already have a few specific requirements in mind. Review collected by and hosted on G2.com.
I'd like to see more detailed information about international transfer fees, supported currencies, and processing times. These things can make a big difference when choosing a provider. Having more of that information available directly would make comparing options easier. Review collected by and hosted on G2.com.
