The fact is that Jazz is better if you're in a big fire-fight, because he can resist fire with his helicopter ears.
But Spaz can move much faster, tho he can't resist firepower that easily. His jumping is very good.
As far as Lori,  her jumping skills SUCK. No offense, but they do. She's cute, yeah, but fighting is everthing here.
Tips: For Jazz, wait below narrow vertical drops like this, then when the Other player falls close enough to the ground for the uppercut, then smack him:
|O|

For Spaz, if people are chasing you in a narrow hallway, turn back freeze him and sidekick him.
As for Lori, I can't think of anything.
I'm a real newbie to the multipalyer world, so don't listen to me.
