None that I've noticed. It IS, however, slightly smaller (width wise). More compact, maybe, but yeah, it doesn't fit other brand beys at all, and it MIGHT be lighter, I don't have good enough scales to check (maybe they changed something to compensate or the paint adds a little weight, IDK). Didn't really notice anything different from how it should perform though, though it's been a while since I used my original Driger S.
On the upside, the Metal Change tip seems to fit fine into my old Hasbro Driger S's base.
