out of those two i gotta go with the testors, it just looks more like ......... well something i like
At least the Testors kit had the option for a framed or bubble canopy and I preferred the bubble canopy over the framed option. The kit overall was too small for the stated scale. Of course applying a bit of scale-o-rama and turning the 1/48th scale kit into a 1/72nd scale model would be an option.
The Monogram offering was nicer looking but that rotating weapons bay was kind of toy-like. I liked the little stealth missile but had no interest in using that in the kit, preferring to find as many as I could for use on other more conventional aircraft as a futuristic missile. Never was satisfied with the scale on the Monogram kit either, again, too small for the stated scale and scaling down the 1/48th kit to become a 1/72nd scale or 1/144th scale aircraft would have been the best way to solve that size problem.
It would have been nice if Monogram actually did have a 1/32nd scale version, that would take care of the size problem when you stuck a 1/48th scale cockpit in it.
