I've noticed both have their advantages and disadvantages. One thing I really dislike about iOS version though is how cartoonish it looks, with all the rounded bubbles and text. I like the latest Android update that added text to the fight/hire/date buttons.
Volleying is easier on android Gifts can be spammed on android Gift screen and trade screens reset to updated position on iOS. Fights could be spammed on android but I've found that if I cue 3 battles, my game freezes permanently and I have to restart it. A.t.a can you get on that glitch? I experienced it a lot during the recent mod crate war. Dorms/avi appearances are gay and equal on both. I like scrolling through showcases more on my droid than on iOS. Not sure why.
