Not that much actually. Compared to the MMS version she has better proportions but I'm just not a fan of Fraulein's sculpt > articulation. It makes her limited. The stand doesn't really work that well either, but she can stand okayish without it. What I do like about her is how she looks more rounded compared to the MMS version. I'll try to get some shots up by tomorrow.
The sad thing is that I'm going to buy Yoko again when the new version comes out, I'm a huge Yoko fan and none of the PVCs have appealed to me so far.
