Browning Xbolt Speed 2 vs Winchester Model 70 Extreme Tungsten?

[Bowjack]

I am looking for a new rifle. How does the new Xbolt Speed 2 compare to the Winchester Exteme Tungsten in terms of performance and accuracy? It appears that some folks love their Winchesters and others find the picky with ammo. I love the Model 70 but I am looking for other opinions and/or experience.
