There was an excellent comparison article/build-up of all three way back in "the other" magazine. Fuzzy memory tells me the Revell got the nod for the best (most accurate appearing) engine, but all three had strengths/weaknesses, but nothing terrible. Mixing and matching could net practically any body style/chassis available. Cool stuff. Incidentally, this is one of the kits that showed up at our Ollie's store a couple years back for $8.99!
