Both are very good but I like to go Austins restaurant and The Pappa's restaurants are great and fairly in Marietta. Old Mill Restaurant, Seasons de Provence, and Fuscoe's are great and upscale restaurants that are in historic downtown Acworth. Of those three, I'd go with Seasons de Provence. Caper's, in downtown Kennesaw (right down the road), is really good too.
