Stealth fighters are the best for all the reasons already stated by duke o' york, and my favourite is to use them in conjunction with paratroopers, to circumvent AI defences of Island hopping.
Fly in, attack AI city until one movement point left, and when enemy unit flag drops switch to paratrooper to take the city, then switch back to Stealth fighter and fly in.
Howies are good to but they don't look as cool and aren't much use in archipeligo maps.
