I love my 1/55 reissues (as well as my Yamatos) and my Jetfire. I can't quite put my finger on it, but it seems that the quality is actually better in my 20-year old (Bandai) Jetfire than the Bandai reissues...
Anyway, I think playability (is that a word?) is important, and the 1/55s have that perfected.
BTW, this may be OT, but does anyone ever think of that old Beastie Boys song "Brass Monkey" when they read "chunky monkey"? Brass Monkey, that chunky monkey...
