I've had varying degrees of success with various planes vs GV's.
JU-88's with many bombs can work against mass GV attacks pretty well, either in dive bomb, or level role. The Ki-61's cannon has worked well for me as well. The Yak-T 37mm another good choice. Then there are IL-2's, Mossies, and so forth. I have better luck with cannon than JABO ord attacks. Others are very good dive bombers.
Depending on your skill, the tarket, and your chosen platoform, it is probably best to attack the tracks to immobiize it, the top of the turrent to knock it out, or hit it from the rear in the engine compartment, again to immobilize it.
