Hah, coincidentally I rode next year's version of all 3 at the Stratton demo days for shop employees this week and this is strictly MY impression of them. For the record I'm 5'9 and weigh 150. Rode the k2 www rocker in a 148 and absolutely loved it (for what it was). Super buttery fun mess around jib board that is cool because you can ride short 'cuz of a longer effective edge, would definately get it to add to a quiver. (Know I'm gonna get a lot of disagreers with this but) absolutely hated the bataleon airobic (151). Didn't think it was lively at all, didn't impress me on grommers, rails, buttering or anything at all. The nitro sub-pop definately impressed me the most. I rode the 148 and it was an amazing combo of soft but REALLY stable for a soft 148, probably because it comes back to camber towards the tip and tail. Still really fun to butter on, hit rails with, and hit small to mid-size kickers. Out of these 3 I would definately recommend the sub pop, its an awesome jibby board that still has a little pop and stability.
