The main difference I have noticed is that I never have to fill up tanks, and I never run out
I have a 3 tier brew sculpture from Morebeer (10 gallon pots/5-6 gallon batches). Never have a problem. Often have multiple burners on at the same time. No problems.
I would hate to have to go back to using propane.
