Need Help. Tenmile vs Mark 5

[Djasi1]

I'm building my next hunting rifle, and I am looking to put a good piece of glass on top. Borrowed a Vortex Viper from my brother for load development and I'm sitting at under .5moa with just two ladder tests for powder! I will be putting it on a Tikka in 6.5 PRC. I will be using this rifle for everything from whitetails in dark timber to Mule deer at longer ranges (400+) and rock chucks as far out as I can spot them. Has anyone out there had the chance to compare the Tenmile to the Mark 5?
Is the Mark 5 worth the extra cost?

Thanks in advance for your thoughts and information.
