If you like TBT the airobic is a fun board. It hasnt changed in 3 years or so. It looks like you are on the east coast, people complain about tbt edge hold on ice, I have never noticed it. The airobic has very mellow TBT so is an easy board to transition to tbt-wise.
Comparing it to the evo, the evo will be totally different. I rode a revolver for a while and noticed very few similarities to the airobic (parkbaord in my case) If you want a soft board that is fun to screw around on the airobic is good times. If you want something to ride all over the place and lay down gnar carves on it is a horrible choice.
