Modus has completely different skillset. Modus is great at certain things, but tends to play up his style too much. He doesn't branch out enough, I find, but when he does it seems he's certainly capable and competent. The issue with Modus is that he can't seem to get out of the early 2000's mindset of design, where everything was metallic and fused with 3ds Max effects.
Jarosh is a master photoshopper and great at animating. I haven't seen his work outside of photoshops, so I don't know.
But for the sake of being modest, they'd probably both kick my ass.
