I don't think it's even arguable, iOS App permissions are better, it's not just 3rd party apps, you can also stop built in apps like Safari and even Maps from using location data if you want to. I'm probably one of many who have switched from iOS to Android, I've been using a Nexus 5 and Android does have many advantages but generally I think I'd still rather use iOS again, this app permission thing was one of the very first problems I noticed. For example I paid for Angry Birds Star Wars 2, and Rovio are a massive billion dollar company, yet for me to run this game I need to give it access to "take pictures and videos" and access my location... you gotta be kidding me.
I also don't get why I can't block certain permissions and still run an app, i've looked on various forums and devs come out with the same lame excuses about apps crashing etc etc, I think that's garbage. For example on iOS I used to play a Call Of Duty game which needed access to my phone's microphone, I know exactly why it needed that as the game had online multiplayer and this would be for voice chat purposes but even then I could block it and play the game pefectly fine. I could still use Whatsapp for text messaging on iOS while denying it access to my camera/photo gallery, and on Android I wouldn't even be able to install it
I think a year or two ago Android probably was better than iOS but apart from things like having root access, I don't see any advantage to using Android for me as on the everyday things Android lets me down. Email is rubbish on Kitkat, the client is pretty poor and not as good as the one on iOS 7 which means you gotta pay for an alternative (you can't even empty the deleted mail bin/folder), I generally find a lot of the apps to be more expensive than on iOS and one other that really bugs me is that not a single music player/podcast app has an onscreen volume slider like nearly every single iOS podcast/music player... yet these are supposed to be touchscreen phones
Android apps seem poorly optimised too, GTA Vice City should run brilliantly on my Nexus but it lags at certain points, whereas on my crusty old iphone 4S it runs perfectly, and other apps that I use daily like Tunein Pro have less features than on iOS too
