That's tough. Most similar bikes I'd say you're an XL with zero doubts. I'm 5'9" with T-Rex's ape-index and other than the way-to-tall seat tube I've been enjoying a large. The XL has another inch longer seat tube over the large so it will really come down to how much drop you want to run.
I mean, and also the terrain you're riding. Tight, twisty, east coast single track going down a size and running a longer stem is going to work great. For the steep local riding I wasn't willing to give up the wheelbase to size down to a medium.
Hope that's helpful!
