We always keep a bottle of Sweet Baby Ray's on hand, but it certainly is sweet. My son bathes chicken fingers in it and if you use it sparingly, it is great for quick re-heated pulled pork (with a little heat added).
My personal favorite is Dreamland, however I doubt you will see it in stores outside of Alabama. It is not sweet, but tangy and spicy. I guess it is kinda similar to Stubb's.
