ahh, I have the "high number of parts" deal for you
a 1/48 scale Hasegawa Tomcat,,,,,,and for honorable mention, the 1/72 scale counterpart
other people, including Hasegawa's older tooling, were able to do it in about half the parts count
as for "best brand", I am sorry to say that there is no blanket "best brand", not even if you narrow it down to one genre, such as "best brand of 1/72 model aircraft"
here's a short list, going by the fact that I wanted the "best model" of each aircraft type listed here
F-4 Phantom,,,,,,,,Hasegawa, out of all the many, many manufacturers
now, that makes you think that you should buy the Hasegawa Crusader, Intruder, Skyhawk and Corsair II to go with it, right?
Nope
Best Crusader,,,,,,,Academy
best Skyhawk,,,,,,,Fujimi, Esci, and Airfix
best Intruder,,,,,,,,,Fujimi again, with Italeri a close second
best Corsair II,,,,,,,Fujimi again (grafting an Italeri nose onto the Hobby Boss body is okay, too)
best Skyray,,,,,,,,,,Tamiya,,,,,,trick question, though, Hasegawa never made one
best Cougar,,,,,,,,,,,Hasegawa,,,,,,,another trick question, Hasegawa makes the only one
you will find some of the same things happening in 1/48 and 1/32 also, and in Tanks, Ships, Prop planes, whatever
