There IS a reason why the good majority at least all the better music software is designed for apple.
Its a little thing called latency. Apple is way ahead in handling latency issues such as found in midi.
There are many wonderful music apps for Ipad that you do not get with android.

If you just need it for viewing lyrics either will work, but for midi apps I'll stick to apple until android can catch up.
