Both planes are lookers... but the warhawk is menacing while the spitfire is more stately.

I have heard good things regarding both kitmakers but I have personal experience with WM and I have been extremely satisfied with them. All their kits go together like lego.

The other thing is the rotating retracts of the warhawk. I have mechanical ones for the Corsair and I can't say they are trouble free. Be prepared to invest time in those.
