A6M5
This plane is a clear improvement over the A6M2, and has good flight characteristics. The main drawback is a lack of armor, plus the smaller MGs.
Max range of (12) means they are most useful of the 3 for escorting Betty/Nell/Frances at range (though you can use Oscars)
This plane requires very little investment however to get before the Hellcat; focusing on the A6M5 does allow you to save supplies or devote R&D elsewhere. 3 Factories should be plenty for research and production.
A6M5c
This plane is slower and less maneuverable than the A6M5, but is tougher; has armor, plus the best firepower of any Zero. Is it worth the tradeoff in speed though?
This plane will require some investement to get in early 1943, at least 6 factories IMO.....
A6M8
The best all-around combat fighter of the 3, no question. Is it worth the tradeoffs?
RANGE is an issue, as the max range with droptanks is 8; that is max strike range on CVs, so is risky, and is an issue for CV use. They are not useful for any long-range escort.
They will also require an investment of 8-ish factories to get at same time as Hellcat
Overall, I am inclined to stop with the A6M5 and save the valuable supplies for other uses, but curious your thoughts
