The A6M3 32 is inferior to the 22 for a few reasons.
It has less range, and poorer armament.
The A6M3 22 uses those wonderful Type99-2 20mm cannons. The A6M3 32 uses the Type99-1.
The Type99-1 carried 60 rounds per gun, and those rounds were woefully slow in the muzzle velocity department. The Type99-2 carried 100 rpg and had substantially higher muzzle velocity.
The Type99-2 fired a round as heavy, or heavier than the Hispano 20mm, though the ROF of the gun was about 1/2 that of the Hispano.
Anyway, the A6M3 22 would be a much better Zero option than the A6M3 32.
...also the A6M5c would be a very nice addidtion to the Zero stable. The "gunboat" of the A6M series, it carried 3x13mm+2x20mm Type99-2. However, it used the same Sakai engine as the A6M5a, but with about 600lbs more wieght! *yeck* Still, it would be nice option zero to have, and if you put the 250kg bomb rack on the belly, you get the A6M7!
