F4U-1C:
Fast, maneuvers well at speed, devastating punch. Pretty good zoom, rolls fast. Takes a good beating to knock one down. Slow climb and acceleration the worst downfalls.
109G-6:
Fast, great climber and accelerator. Basic guns a little on the weak side, but gondolas improve punch markedly (at the cost of maneuverability and climb). Handles well at mid to low speed, but at high speed it gets very heavy at the controls.
190A-8:
Rolls very nicely, great intial turn rate, great firepower. Downside is that after you slow down you are in trouble, even the Hawg will turn inside you. Top speed is slightly mismodeled, so you won't run very far either. Be smooth on the controls and keep the speed up and it's a lot of fun, but Hawgs can ruin your day in a hurry.
