"Jugs" - Awesome aircraft. I believe that the low altitude climb was improved with the switch to Curtiss and Hamilton "paddle props" beginning in '43. Though some believe that paddle props debuted with the bubble canopy models, I think that they were retro-fitted to earlier models in theatre.
OMG, did not the P-47M match the various German fighters climb rate in a tight upward spiral?
I do know that even earlier models of 47s could turn inside most German fighters, something no one would expect from such a giant among single-seaters.
