I don't think there is a difference in the transfers.
The account allows you to load up and convert/hold any number of currencies. For example, I fund the account in US dollars. I can then convert/hol Dollars, Thai Bhat, Euros, Turkish Lira, Etc. in any amounts simultaneously in the account. It also has a debit card that I have been very impressed with. I have used it all over the world and on line with never a hiccup. It also converts to the local currency with any purchase with no fees.
I am happy customer and will use internationally until it dies or something better comes along.
