What is the big deal about bringing your wort to a boil so quick.
TIME! It also means your not under powered and will get a good rolling boil.
Could be hours on your brew day. Also, it's tough to get larger batches (full boil 5+ gallons) to a boil on a home stove, and almost impossible with 10 gallon unless you have a very powerful stove.
