I dunno, but Whels seems to be the most realistic IMHO.
Some of the others I have heard remind me more of a a Piper SkyHawk than a P51.
Whels' stuff is deep and powerful like I would expect 12 unmuffled cylinders of exploding compressed high octane gas swinging a 12 foot 200 lb prop to sound like.
I'll take that $10 now Whels.
