Insanity is an understable driver that Axiom describes as a worn-in Inertia, with more high speed turn and less fade. Average arms will find it flies remarkably straight, while big arms use it for precise flip and turnover lines.

Neutron is the flagship and the one most people start with. Opaque, durable, and available in the widest range of bright colors, with a clean slightly firm feel and solid grip. It's the most true-to-numbers plastic in the lineup, meaning a new Neutron disc flies exactly like the mold says it should. The dense overmold also means it beats in slowly, so if you lose one and buy a replacement, the new disc flies like the old one did. Stiffens up in cold weather and picks up some flex and grip when it's hot without ever getting floppy.
