I am pretty pleased with Jetfire and Jetstorm. They are pretty decent figures.
Not the best by far, but still very good.
One thing I think that lets them down is their short torso. It seems a little stunted, just enough to make it look a tiny bit odd.
I agree with jaydisc on most of what he said, with the exception of the individual vehicle modes.
I think they are alright. The gap between the 2 thrusters makes them look kind of alien, while still being practical. It also reminded me of Star Saber.
I think the arrow head jet mode is good over all.
I just wish that the fins/wings on the sides were supposed to tilt up and not have to miss-transform them to do so.

Spoilers (high light if you wish)
Oh, and they are supposed to be kiddy, or at least adolescent. They appear to be really young in the comics, so I think this is them a little bit later, like a year or so. So it would fit in well with Animated Season 3
