Ok I'll give you backups but I think messages depends on your contacts and what messaging apps they use. For someone like me I only use imessage to communicate with my mum. Everyone else, whether they have an iPhone or an android device uses other apps.
Ya - tough to compare but Messages is a HUGE plus in favor of iOS for me.
FAR better than Hangouts and getting my friends and family to sign up for various third party services just isn't feasible.
Messages is only getting stronger with iOS 8 too.
To be honest, I challenge people the other way - what does Android do that iOS can't. The main things are customization and torrents. There are more specific examples that usually have to do with a certain process (the end task is doable on iOS, but someone prefers a certain way to do said task).
Honestly, I'm getting over this whole argument of which is better and why. Ultimately - who the eff cares? As long as the device you purchase works for you?
Reason I get upset sometimes is when people spread absolute nonsense on these threads. Similar to those of you who push back against the "it lags" comments against Android.
