Samsung Galaxy, I have both and I prefer to use the samsung. (Although I do not have the new s5) But all the screens are pretty much the same. All the iDevice's have the same stuff, but Android lets you do a lot more. Free emulators for Gba and old simulation games, with ought jail breaking/rooting. Also, you can download a lot of better apps, more free ones too. Samsung has like 3 different stores too, and the amazon one gives a free paid app every day. It's mostly just preference, but I highly recommend the s5 if you have the cash
