The 2.5-10 performs better in low light, eye box ,at making better placed shots at 200yds plus and quick shots from 25yds to 50 yds on 2.5x . All of these make the glx a better scope for hunting and to be used in wider open spaces aka (the great outdoors)which is what my intended purpose of my ar10 308 will be used for that this scope is on . The plxc is great at 1x, extremely light and compact,works well with white light at night , works well for combat accuracy out to distance, and has low profile turrets that work well for me to piggy back an rmr style sight. These attributes make the plxc more suitable for home defense carbine in 556 etc. They really are like comparing apples to oranges. I really like them both but for different applications. Even though I can, I would not want use the glx 2.5-10 for room clearing especially with a white light in dark conditions.
