It doesn't matter. :-) If your criterion is "fastest and easiest to pickup", the expected marginal advantage of one or the other is smaller than the time you'll spend choosing between them. The only way to really find a preference is to dive in, learn one, and then maybe learn the other later. There may be some other criteria that decide the issue for you, e.g. market conditions or owning a Mac. But really I'd just pick whichever gives you greater enjoyment. Best of luck! Edit: I did want to say that if you go with iOS, the O'Reilly book Programming iOS by Neuburg is excellent. I felt their Android book was pretty weak.
