You can use any platform that you are most comfortable with. The payment methods are all reliable, if that is your question. But you need to understand that all the payment methods have different requirements and rules, such as minimum and maximum limits, processing times, etc. The specifics are all detailed on the XS website.

They are all reliable... If any of them was not reliable, XS would probably not use it for traders to transfer thousands or even millions of dollars in and out of their accounts in the first place. I think skrill is very good and popular but if you dont have an account there but you have an account on neteller for example, you can stick to it without a problem.
