Uh oh. Let me put on my flame-retardant debate suit on.
Thanks.
The short and simple answer is, IF you desire to save more money in the long run, even if it means to "suffer" the sense of crushing debt longer, then the answer is to pay off the loan with the highest interest first. IF you value simplifying your debts and need motivational boosts to keep yourself going more than you need to save more money in the long run, then pay off the smallest balance first.
