Staggered or the same all around?

Whats up guys, ive been having a hard time deciding what to go with, wanted to hear some opinions on the matter to maybe help me decide lol, im getting XD9's, either i was going to get 10x18 +18 all around, or go with a staggered look, 18x9 +20 (front) 18x10 +18 (rear). I have seen both these setups before but still cant decide what to go with, what do you guys personally think looks better, staggered or not? Any pros and cons?

Thanks :)
