Certainly the new allied especially US guys were better trained in late 1944 than the German new guys, the "Dreitageflieger".....
Excellent summation of the 109 vs 51 fights Hangtime, however you got one vital issue of FACT incorrect.
The 109 is the most beutiful plane ever made, especially the G6, while the P51 is in fact the ugliest.

Happy to correct your error!
BTW: Merlin Spits are very very ugly too.
