Yeah, I'm from Chicago, so I often get SBR for around a dollar a bottle (the smaller one), so I often do taste tests between all the flavors. The original is definitely the best of the bunch.
That said, their are at least 50 sauces I will reach for before I go for the SBR. It just seems really one dimensional and sweet (really just sweet) to me.
But I think a lot of people buy it because it has a cool name. That's marketing for ya.
