Just heard back from Meguiar's and while they prefaced the answer with the major point that it's hard to categorize the aggressive ranking of products easily because they are always a lot of variables involved and variables can great affect the aggressiveness or non-aggressiveness of a product.
That said, if all other factors were kept the same, type of tool, type of pad, same person dong the work, same technique being used, paint system the same for all work, then D300 would rank as less aggressive than M95 and a tick more aggressive than Ultimate Compound.
Great question Mark!
