android.... it's open source, usable on all kinds of (better and more functional) hardware devices, has full compatibility with all the media and software i want, is less expensive, has better/easier privacy settings, doesn't require me to install software on my PC to run certain functions, and is fully plug & play compatible!!!!!
ios is just way too big of a headache to use, requires you to update/upgrade too much, is only compatible on one brand of device (that has limited ease of use) and i fucking HATE itunes.... if you already use a mac, i guess ios is fine for cross-platform functionality.... but if you're on a pc then i highly recommend android.... it just works better, and does not look like a toy.... with ios, just be prepared to spend more money, upgrade more, and have to install software on your computer in order to do things like transfer files....
