I'll list my top picks and explanations:
All-time Favorite:
Ki-84
This plane is one of the best "balanced" fighters. It's got very nice speed, sizable ammo with 2 12.7mm MGs and 2 20mm cannons, excellent turn rate, great climb rate, and the best acceleration rate of all the prop planes.
Downsides are it's got very little WEP, compresses very easily (watch your dives), and is susceptible to pilot wounds.
Other Favorites:
C.205 - great climb & turn rates, good speed, TON of ammo w/ 20mm cannons. I've found it to stall easily though at low speeds
F4U-4 - As someone said before, the best overall of all prop planes (in my opinion). Ton of ammo for it's 6 50cal MGs (no cannons however), superior turning w/ flaps, climb rate is superior, speed is superior. Also doesn't compress easily, and you can drop your gear at 400 kts!!! Woot
Hurricane2C - The best defensive plane in my experience. Turn rate is unbested except for the A6M2. Rolls great, and has nothing but 4 20mm Hispano cannons for offense. Downsides are it has very little ammo, isn't that fast, and doesn't have a great climb rate
P-47D-25 - My favorite of all the heavy fighters. Excellent speed once you get it going, and can actually turn pretty well if you use flaps. Has a gazillion rounds for it's 8 50cal MGs, and you can easily slap some ords on it for ground attack. It also takes a serious beating...very rugged aircraft. This plane is one of the best for town offense as well
Yak-9T - Lots of people don't like this one but I think it's a great little plane. Awesome speed and a superior climb rate. The big thing with this plane is it's 37mm nose cannon. This gun is basically a one shot kill. One hit on a wing will rip it right off. This plane is well suited for defending bases against bomber attacks. It gets up quick and has a huge punch
Typhoon - If you want some quick boom and zoom action, jump in this thing. It is the fastest of all the prop planes, and packs a serious dose of hurt with it's 4 20mm Hispano cannons. It retains E extremely well on climbout, but it doesn't roll or turn well at all. Keep your speed up and don't get too low
N1K2-J - This is another well rounded and balanced plane. Excellent turning, decent speed once it gets going, and lots and lots of ammo for it's 4 20mm cannons. Don't try to outrun pursuers in this plane though, they WILL catch you. I use it for turn fighting and limited boom & zoom capacity
Well those are my top picks.
To the OP: Hope you find a plane that best suits you!
