There are several threads with nearly exact same titles as yours.

here for example is N900 vs Droid vs Nexus. And here is a first hand review of both and several pages thereafter of community discussion.

You are not going to get anything new in this post that hasn't already been addressed many times.. I'd suggest starting with those threads and looking through them, then using the search above with keywords such as "Nexus One" "android" etc... to see many, many others.

If you have a specific question after that.. feel free to ask .
