There is nothing wrong with aluminum....its just a matter of personal preference. One thing I would question is your choice of the 6 gallon size. If you are making 5 gallon batches and you want to do full wort boils, you will need at least a 7.5 gallon pot. If you are doing partial wort boils then 6 gallons almost seems too big. Its like, if you want to upgrade to full wort from partial wort, then you're only buying a slightly larger kettle. Return it and spring for a larger pot....just my opinion.
