MS live mobile search vs Google maps vs others

[nexgencpu]

Just want to know peoples opinions on these multiple beast. It seems that they just go back and forth and add more and more features. But besides these are there any others? It seems tough to find other ones in the market. It also is a bit difficult to find proper comparisons of them. Got this one review of
MS live www.bsday.com/reviews/mssearchreview.htm

But I cant seem to find a nice google vs Ms comparisons vs others
