The ubiquitous German fighter of WWII was the BF-109. In the hands of a competent pilot the aircraft could hold its own against any Allied piston-engined fighter. The highest-scoring Aces of all time got most/all the the victories in 109s. Erich Hartmann is credited with the highest total of all time. In fact, just six 109 pilots (Hartmann--352 kills, Barkhorn--301, Rall--275, Marseille--158, Molders--115, and Galland--104) account for 1305 aircraft shot down!
I'm just finishing a model kit of this potent little aircraft (though nowhere new the quality of the one at the bottom of the page!). But I'm partial to one specific model--the BF-109F. It has the streamlined shape of the later nose, the cantilever tail planes, and lacks the tumorous humps of the G model's cowling gun fairings. If it only had the "Galland Hood" . . .
