This might be some months late, but it would be better if we defined the criteria for each class first. It seems it all comes down to alterations to the user's body from what I've seen:

Emitter: Body does not require alteration to do stuff.

Transformation: Body requires alteration to do stuff. Alteration is temporary.

Mutant: Body is already altered permanently.

The Quirk Navibox right now:

Emitter: Acid, All For One, Attraction of Small Objects, Black Hole, Bloodcurdle,  Brainwashing, Cement, Clones, Creation, Copy, Disintegration, Earth Flow, Electrification, Erasure, Explosion, Fiber Master, Fire Breath, Half-Cold Half-Hot, Hell Flame, Jet, Navel Laser, One For All, Pop Off, Recovery, Search, Shock Absorb, Solid Air, Somnambulist, Sugar Rush, Tape, Telepath, Voice, Water Creation, Warp Gate, Weld, Wood Control, Zero Gravity.

Transformation: Dark Shadow, Foldabody, Gigantification, Hardening, Pliabody, Regeneration, Steel,

Mutant: Earphone Jack, Engine, Four Arms, Frog-Form, Gatling Gun, High Spec, Replicant Arms, Snake Hair, Tail, Transparency, Vines, Zoom

The bolded are the ones that are iffy.
