Grooved/drilled etc look nice, but for road use you will not get any benefit in braking whatsoever.
If anything, for every day use they are more of a pain because:
1. more likely to make clicking noises on braking which can become a major irritation. (personally i didnt get this when I fitted them (black diamonds) but i have heard such stories off other members)
2. pads will wear quicker compared to plain discs.
I would stick to plain and simple discs unless your a track nut or you want it to look "better"
I would advise to hammerite the drums and rims of all new discs you fit to prevent them rusting and looking dreadful, as no matter what brand of disc you fit, you will invariably get this.
