I'll go with Mecha-G Heisei, myself; since Kiryu isn't exactly as extremely potent at his G-Force counterpart at long range, and Showa-era MG... Well, depending on the version he's either the first to go or the second. Considering how high Heisei MechaG's defenses were and how potent his offenses were, he's going to win somehow. All Heisei MechaG needs to do, really, is stay out of either foe's comfort zones and put up a constant offense.

Showa has the reflector shields, but Heisei has the diamond armor (and even tanked six (or so, not entirely sure which number it is) Spiral Rays in a row without it). Both have missiles, but Heisei has both eye beams and the Mega-Buster, as well as Shock Anchors, jets that enable flight and the Garuda to combine with to form Super Mechagodzilla; Showa MG only has eye beams, missiles, a reflector shield, flight and a flamethrower; and really only the missiles could end up being a problem unless Showa MechaG can get into close-quarters combat; which neither of them are very amazing at. All of Showa MG's projectiles except the missiles and darts are energy-based; and thus only fuel for the Plasma Grenade. Kiryu's going to get pulverized quite quickly by one of the others spamming him to bits; especially if he's already berserk, so it's really down to the G-Force Mechagodzilla against the Simian Mechagodzilla; Beam Spam VS. Projectile Spam.

And considering the feats of the two, one nearly killing Godzilla and the other, depending on version number, either constantly stiffarming things and spamming projectiles or hanging in the back, spamming projectiles and going down like a chump, I guess Heisei Mechagodzilla might just pull out the win here.

But that's just my opinion of course.
