Auburn 3rd year here (went to Mississippi State for undergrad). Was also IS auburn, OOS MSU. Unless something DRASTIC has changed, they are most definitely not the same cost. For transparency, I pay about 11k/semester for IS tuition at auburn. I would’ve been paying about 25k/semester for OOS MSU. I got in at both and ultimately made my decision off of money, and I regret it. If finances are truly (doubly check!!!) the same - Mississippi state is absolutely the better program. DM me if you have any questions!
