Google Maps API or Microsoft Live Maps?

On the site, our members will have profile pages listing where their organizations are located (our members are scattered throughout the world) as well as other pertinent information for the general public. It is a non-profit organization, so funds are tight. My question to you, dear /. readers is this: If we include maps, which API do we go with: Google or Microsoft? We're in a Microsoft environment (hold the snickers, we're non-profit and Microsoft basically gives us everything for free so there is a sense of loyalty there) but the ubiquity of Google may be enough to sway us. Has anyone used either extensively? Used them in conjunction with .Net? Finding rational opinions online dealing with anything Microsoft is next to impossible, but I'm hoping one or two /.'ers come through."
