"I asked for some info from your side of the argument to help me objectively look at which option works out better. "

Be more specific with the information you ask for, and you will get a more direct answer. Simple.

Hell, take 2 mins out of your day and do an online quote.

"are the lease rates variable or fixed"

Ask the lessor. Most I have seen are fixed.

"what is the maximum balloon payment"

Will vary depending on the lender, the purchase price and the make/model leased

"monthly fees etc etc."

Will vary depending on the lender. Fees typically added on top, but generally you can negotiate to have them waived.
