!90A-5s shouldn't mess with N1k2's unless they have an energy advantage.
But against the Hog or the Stang the 190A5 wins so long as he has about the same fuel load and only lugs 2 cannons. When you engage a Hog or Stang or Jug or P-38 1 v 1, you are rolling the dice: If he is carrying a larger % of full internal fuel than you, you win. If he's carrying significantly less, you lose.
The A5 is also a pretty good stall fighter with flaps down and low fuel.
The 190A8... well, I don't know, stick to vulching and running.
