I've been using Sweet Baby Ray's for a long time and always get raves on my ribs.  My mother-in-law saw the sauce on my counter once and told me it was voted best barbecue sauce in her gourmet group.  After trying my ribs, she heartily agreed and now that's all she buys.  I admit, the sauce is good.  It's sweet, full of flavor, but not spicy hot.  Every now and then I stray, but I always go back.  Nothing beats Sweet Baby Ray's.
