Reloadable Visa Card vs. Reloadable MasterCard?

Today, I received a very late birthday present from a friend of mine. He gave me a MyTreat Prepaid Visa Card. I used it for some stuff and fell in love with the non-existing annoying process of using a Debit Card. This got me wondering, so I did some research. I found out that my card can't be reloaded but their are ones that can. I noticed that Visa Reloadable had a dumb monthly fee while the MasterCard Reloadable didn't. Obviously, MasterCard would be the better choice here but can you do some extended research on both cards please?
