The first question to ask yourself is "How much am I wiling to spend".
Then we can give you better guidance.
The biggest advantage to the hash marked or mil dot reticles is for rapid follow ups. They create a grid whereby you can spot your hit and put that spot on your target and give it another quick shot.
My preference is for Leupold VX3's, VX6, and VXL's along with IOR Tactical scopes with the MP-8 reticle. In the Leupy's I like either a mil dot, varmint, or B&C reticle.
The Zeiss Conquest are also really nice scopes that are pretty much the top of the line in their price point. Set up right their rapid z reticles work very well too. I have several Conquests with mildot reticles on predator hunting rifles and love them for the quick follow ups.
The IOR MP-8 reticle is however my favorite of all.
