Eyries are good skirmishers. Very good vehicle hunters, with large numbers of small weapons to immobilize and Talons to exploit range 0 physical attacks where vehicles are incapable of responding. Jump 7 is very hard to hit; use it.
Gyrfalcons are the Rifleman 3N on four kinds of steroids, speed, and cocaine. They can run or jump for a +4 to hit depending on what you need your attacker mod to be, they have an armament very similar to that of a Rifleman (except obviously Clan, which means your ideal engagement range is 25 hexes not 10), and it has Reflective armor so the usually natural predator of fast jumpy things (pulse lasers) are almost totally useless.
Shrikes are... fast for Assaults (5 hexes). I personally enjoy the one with the Ultra/10, but the 2 column for clusters is just a little bit too unreliable for the twin Ultra/5 version to be very good. I love the whole look, but you can make the argument that it's not very good.
