Google Play Store has less regulations on DMCA and they take less of a cut for your earnings. It is more oversaturated however so you're gonna have to do some killer advertising on your game. 

Apple Store is less cluttered but they are way more annoying about DMCA and iOS porting is a huge pain in the ass. A friend of mine has been developing a game for Iphone and he has to do a whole bunch of crap like memory allocation and kernel fixing.

Also in the Apple App Store, the "New Games" aren't displayed until several scrolls down. 

If you're viewing it on mobile, the categories usually look something like this:

What to Play this Week

New Games We Love                            (all the way down here!!!!)

So unless your game can fit nicely into one of the first few categories, good luck on getting onto the front page of the App Store.

I dislike all the app/game stores I've tried except the cool developer-oriented ones like itch.io and gamejolt. I use itch.io as my main portal for desktop/web/android games largely because it's fairly polished, I have a lot of control over it and can reasonably customize its appearance, but of course I have to use the App Store for iOS. Google Play was great for getting lots of downloads for my free apps but paid apps are another story and you have to decide once and forever whether an app is free or paid (so free with IAP  is probably the way to go) and there are a lot of other hassles like having to list a support email address which is then spammed by ad vendors and publishers looking for desperate developers (sad to say, I've had disappointing dealings with makers of Android tablets for kids). I got my most steady revenue for paid apps on Steam, the App Store, and the Amazon Appstore (and briefly but brightly, the Nook app store), and I made a few bucks on the Microsoft Store.
