All I can say is the vast majority of people out there seem to be enjoying the iPad Air + iOS9. If the OP has done a full restore through iTunes and is still having issues, it is more than likely a faulty unit.
I haven't had ANY issues. Sure, on the iPad Air 2 I'm missing the side by side multitasking, but everything else seems to work just as it did before. I didn't even notice a big hit to performance when I upgraded, no freezing or anything.
