I personally hate draining boards, I think they look terrible and the higher-end the kitchen the cheaper and nastier they look (even when they presumably aren't). When I was doing my kitchen I left it out completely and am so pleased I did (I didn't have the option to have grooves instead as my worktop is only laminate).
I do have a dishwasher, but whenever I need to hand-wash something I put down a tea towel to use as a temporary "draining board" and I put it away when I'm finished. An unexpected upside of this is that I rarely just leave things out to drain-and-dry, I nearly always actually dry them up and put them away (my track record on this issue would not lead you to suspect I had any drying-up skills at all, so this behavior is a big surprise).
My aunt and uncle have a stone (sorry, don't know what kind) worktop and they have grooves instead of a draining board and I've always thought it looked great. It certainly looks much more high-end than a stainless steel draining board. I think they have it about 15 years now and it seems to holding up perfectly.
