Love helicopters.
I have only flown in crappy civilian Sikorsky and Eurocopters, but the inner Rambo in me has a real affinity for attack helicopters.
I matched up the AH-64 Apache against the KA-52 Alligator, and break down their aerial prowess as follows: Alligator is more heavily armed and slightly faster. Apache has better range and can reach higher altitude. Probably a reflection of core miltary doctrines of their respective armies.
