Mortgage broker saying 15 and 30 year fixed rates are the same? What gives?

I just finished submitting my paperwork for a pre approval, and my quotes for a 15 and 30 year loan rate are identical - 6.5%. This seems kinda nonsensical to me. I’m looking for a 200k loan so it’s not the biggest difference in my monthly fees but a credit Union nearby is offering 6% on a 15 year loan - is it even worth continuing with the broker? I’m not sure what the benefit would be, would he at least save on the paperwork side of things lol?

(Obviously) first time through this process, any insight would be appreciated.
