If they are really close in sharpness as you seem to imply ("if you look real close it has a little better sharpness"), then I'd take one with less reflection.

Rational being if I really needed the absolute maximum sharpness for the application, I wouldn't be choosing a type with non-glare treatment in the first place - which usually visibly reduce clarity over regular type.

If I did need anti-reflective quality for a particular application, being sharpness being close, I'd be choosing the one with maximum anti-reflective quality. Little (very little) less sharpness is a price worthy of not having a presentation where details are hard to see anyway due to heavy reflection of existing harsh and uncontrolled lighting or what-not.
