I think it's all the commercials

. However, it seems like its always said that there are more/better apps on iPhone. I'm just a little new when it comes to android. None of my friends have it, whereas I'm slightly versed in iPhones.
I wouldn't rely on commercials for an adequate comparison.
Skype isn't very great on Android. There's no video support, since most of the phones don't have dual cameras. That's one area where iPhone is still king.
I've used Skype on an HTC Inspire 4G, on an iPhone 3G, iPhone 3GS, iPhone 4, and iPod 4Gen, and without a doubt, the iOS is absolutely worse with Skype. Cannot tell you how often the stored server messages lock up the app if you send hundreds or more messages a day for the app to backlog, which it makes sure to do first thing you open a message to send to a person. Annoying as [censored]. Truthfully, though, I don't like either mobile Skype app very much. I'd just steer clear of Skype apps at all no matter the mobile platform if you actually message a lot with the PC version.
It is true that your selection is slightly larger with iOS for reasons described already -- they've been out longer. On the other hand, the development of Android has been nothing short of frenzied, and the apps/games I've seen so far have been quite nice, as well as I have to side with any OS that allows more room for the insane customization Android does.
OP should do research and figure out which is best for them, just don't rely on commercials to make your decisions. :facepalm:
