I don't think it is really a contest in terms of performance. I agree the stage 2 looks sexy, so it comes down to what you want out of it. The stage 2 is still has great performance, just not as good as the boss. So if you want great performance with the looks of the stage 2, instead of the boss performance, than go with the Roush.
