I like the Artoo, just for the fact that it appears to be a repaint of the Sneak Preview R4-G9 sculpt, and not a rehash of the VOTC version.
Don't care for the VOTC version at all, compared to the (far-superior) Sneak Preview model.
I actually wanted an Artoo made out of the R4-G9 version so much, that I attempted to repaint one, and I have all the figure-painting skills of a drunken goat. Needless to say, it did not turn out well.
