I use atacr 5-25 ffp, and ten mile hx 3-18. To my eyes the atacr has the best glass. I like the ten mile on my hunting rifles for a little less weight. Both track and hold very well.
Had a nightforce nx8 2.5-20 and I tried to like it but it was difficult to get behind. Glass was great, turret clicks were great but the eye box was horrible. If I ever buy a NF again it'll be the nxs 3-15. I just didn't do enough research and really didn't know what I wanted. I recently got a Trijicon Credo 3-9x40 mil holdover and I really love this scope. The eye box is so easy to get behind, the glass is great and shooting steel at 750 is no issue with 6-9 power. I'd like to get another dialer eventually but I've found the holdover easy and quick. Good luck on your search. Read everything you can because sometimes what you think you want is not what you really need in field conditions and you'll later regret your purchase.
Figured I would circle back for the next guy looking. Ended up at Cabelas twice to look at NF, looked at the 2.5-20 and 4-32 NX8. Feel and look of the scope looked like quality. the 4-32 tunneled really bad and I couldn't get to fit my eye very well, the 2.5-20 was better. They were both FFP scopes, and the cross hairs were useless, until cranked up half way, which is possibly expected on FFP. However comparing both of those to a Zeiss V6, glass was subpar, was dark in a light up store. Didn't compare side by side but same day looked a Vortex venom and that glass was all of the NF. Bottom line here, I wanted to get the NF really bad, but I couldn't handle the $2k price tag for average glass and tunneling.
Ended up taking a runner on a Trijicon tenmile 4.5-30. Glad I did. Glass is clearer and brighter and is clear edge to edge, with no black ring like the 4-32 NF. To be fair the Trijicon does tunnel some at around 25 power, but again is expected. I got the MOA long range reticle, which Im not crazy about, but it is simple and uncluttered. Really like the scope. Dials move smoothly IMO, maybe not as crisp as the nightforce. Haven't shot yet, just mounted and played around with it outside. Trijicon also came with Neoprene scope cover, Tenebrex scope covers, sun shade and lens pen
