They're good for being actual foils to STK
Jet has the same arrogant, hyper competitive attitude as Sonic but without the heart of gold
Wave has the same passion for mechanics as Tails, but is overly arrogant rather than humble, and acts as the big sister of the group as opposed to Tails being the little brother.
Storm is basically the inverse of Knuckles; he's basically the braggadocios muscle that's fiercely loyal to Jet and the group, whereas Knuckles is the stoic muscle who's fiercely independent and is prone to butt heads with Sonic.
