Quote - Interesting.  Is that why Genesis figures have that super smooth look?  Someone described it as looking like a blow-up doll.  Unnecessarily rude, for sure, but I kind of see what he meant.

Not really. Most of what you've probably seen is people using GenX to copy over morphs from Gen4 characters without modifying them so they lose detail... copying high details to a lower poly character. You won't see the benefits until you leave the Gen4 morphs behind and start from genesis for creating your characters.
