I had a KAB4 burner first (Bayou) and it was ok. Got the Blichmann since I needed a second burner, with long legs (got the longer legs for the Blichmann) and a short time later I sold my KAB4 and got a second Blichmann burner. The are quiet, use less fuel, and the housing is all stainless steel. Some people have modified their Bayou burners to try and replicate the performance of the Blichmann, but that's one area I'm not about to go messing around in. I'd rather get the right one the first time. I actually wish I had not bought the KAB4 first, since I took a loss on it (even though it was only a few months old).
