Skeetshooter, I'd think your answer might depend on what app you are using to do your compositing. If you have a chromakey function in your compositor, blue or green is probably the best choice because the software should handle the removal of those colors automatically. If you are seeing a border, than either the software isn't quite up to the task or something else is out of whack.

BTW, for compositing, uncompressed video is the best way to go, if it won't break your hard drive. Video compression can introduce artifacts that are difficult or impossible for the chromakeying software to remove. (A lot of chromakeyers originally had problems with DV video for just this reason. I think this has improved since, though.)
