If I were to choose just one hunting scope, it would be Tangent TT315H with the mrad reticle.
However, it is well above the OP's $2000 limit. Given his reticle visibility requirements, I'd consider Leupold Mark4HD 4.5-18x52 with illuminated PR1 Mil. The new Telson Toxin 3-18x50 has a nicely visible reticle. Both are in the $1500 range.
I am very fond of Vortex Razor HD-LHT 4.5-22x50 and still have one (which is not mean feat given how many scopes come and go here). However, the reticle on the Telson and Leupold is a little more prominent on low power.
If you want SFP, you can get S&B Zenith 3-12x50 for $2k.
