All the scopes will work well. I posit your choice should be influenced by whether you prefer fixed or variable, the type of rings you prefer, the reticle you like, and a gloss or matte finish.
I like fixed scopes.
I dislike Talley Lightweight rings on most rifles and Leupold Dual Dovetails on a Rem 700, but I like Talley Screw Lock and Fixed rings. For my preferred sight picture I need an extended front base when using a Leupold 6x42 and 2.5-8. 3.5-10 and 6x36 perfect sight picture without extended base.
If you want a Boone and Crockett reticle you'll have to pick a variable. Heavy Duplex? 6x42. Long Range Duplex? Either the 6x36 or 6x42.
My choice would be a 6x42 matte finish with Heavy Duplex in Talley Screw Lock rings with an extended front base. Second 6x36 LRD, no extended base. Third 3.5-10 B&C reticle. 2.5-8 eliminated in my mind.
