Tall grey uggs or tall chocolate uggs?

i wear dark skinny jeans, and dark leggings (brown, black, and navy). my top color ranges from mostly navys, whites, greys, and browns. i have had short chocolate uggs before and i liked them, i just don't know if i should get grey. my cousin has grey and they easily got stained by the snow and can't get cleaned. i sometimes get them wet or snowy, so which would withstand that better. i have fair skin and light brown hair. help!!??
