I have the R2 and I like it. It's marked at 2 MOA increments which is a little less *busy* than the 1 MOA hashes on the R1. The R1 will be a little more precise for holding on target. the R2 might be a little better for night shooting with an illuminated reticle since it's less busy? I think both reticles are great and your choice should be based on your needs and preferences.
For *me* the NP-R2 is a perfect reticle for hunting. It's very simple to use and easy to interpolate between 2 MOA. The reticle allows for holding on up to 20 MOA of drop without dialing, which gets me to about 1000 yds with my bullet trajectories
