I agree!!! The Corsair or T-28 is better for a beginner in warbirds, but the Pony flys the most stable.
After about 10 flights with the F4U or T-28, you'll be ready for the Mustang.
I'm still thinking of getting the Corsair, but I'm also planning a second Mustang. Decisions suck eggs. Where's that darn winning lottery ticket???
