I haven't really gotten 'in' to a novel for a long time...but Airman...it just...SWEPT ME OFF MY FEET.
As everyone basically stated before, it combined all the perfect elements. One of Eoin's masterpieces apart from Artemis. I mean HMI, Supernaturalist, Wish List, etc, are all good and respectable, but Airman is, to me, the only one that can compete with Artemis.
As for who I like more, Artemis or Conor? Conor's got a decent heart and is intelligent—basically the perfect type. But Artemis is less indecisive I guess. Conor's smart, but not GENIUS smart. Though he's more believable as a real life person, I guess. Still, he doesn't have the dressing habits of Artemis, nor the insane phrases Arty comes up with. So I'd have to still side with Arty...though Conor comes DAMN close!
Bonvilain...a vilain who actually doesn't get the support. For instance, Snape and the Malfoys from HP still have fangirls, etc. With Bonvilain, you JUST have to hate him!
We were talking about it on msn, (me and smellycat), I liked it more than AF, I think it's because I warmed to Conor more.
Maybe it's because he was pure hearted from the begining, rather than bad then good.
It would make a cool film, but if they go at the same pace in which they are making AF, I may be dead by then!

Hm...I prefer evil then good. Not good then evil. But I guess you can argue either way. Evil who turn good show that at least they can CHANGE for the better. But I guess good who turn evil people can adapt to survive...*shrugs*
