I prefer asphalt, ice and snow melts quick in the winter, can throw salt on it if need be. It does need sealed every couple years and crack repair is easy. if it's a thicker asphalt job you won't have the issues a cheaper job done ( ex a lot of MI, Dominion etc developments).
Concrete does look nice and I like that a BB doesn't get dirty on it like asphalt, not that it's a huge deal. One thing about concrete is it's gonna crack eventually no matter how good of job it is. It's the nature of it, it dries out and shrinks and cracks. It doesn't help you at all in the winter months, no melting of ice or snow to the likes of asphalt and salt is a huge no no.
