I've only got the one MSD KDF Bory from Luts, little guy. My favorite mold is the Dollshe S.A. Saint, too bad he isn't being sold. I'll have to keep my eye open at the Den of Angels marketplace.
But yeah, I've never had experience with big dolls, but aside from my Bory, I really think they look better anyways. The really small ones freak me out a little, haha.
