Graphic wise, the game looks the same on iPhones, Android smartphones and tablets.
What matters it the amount of map that you see in one screen.
And the amount differs from resolution to resolution. Here is a comparison.
iPhone 5 that has 640 x 1136 resolution and Nexus 7 that has 1280 x 800.
If you want to play the game in perfect conditions, you should try a 10 inches tablet.
