Having extensive experience with both, I can answer fairly.
If you can afford the airfoil rim (although I think they are sold out
and the machine broken, I think I saw in another post) and intend to get
into MUni, or Rolling Trials, or are heavy (maybe you have heavy friends
that you want want to let them try), you will appreciate it's
strength.
The stock on is steel, it's weaker, it can rust, and you can fold the
rim over much easier. The rim will teach you to ride with finesse, I
was able to fly through rough technical trails for a whole year putting
way more use than the average rider, I garuntee that.
I think I am such a strong coker rider because of the skills I needed to
develope to push the coker to it's limits (and almost beyond)
I have only used brakes with the airfoil, but 'they' say the stock rim
wobbles too much for an effective brake. I think it would be less than
ideal, but certainly not ineffective (no need for too much brake power
on a uni anyways)
So get the airfoil if you can, but don't think the Coker will crumble
under you immediately (although keep that in the back of your mind at
all times once you start riding hard)
