I've been playing biplane vs biplane dogfights lately and those...so far...are the most fun dogfights I've ever played in IL-2.
What was your favorite dogfight?
EDIT: Just had a priceless moment. I'm flying the Avia 534 against Russian I-15's. I tore one in half and his wingman ran into the pilot who had just bailed out and crashed. I wish I had a video or screenshot for it. That'll never happen again.
