Everyone is mentioning hunting, but I have one on a match/misc rifle in FFP with the Mil-XT reticle and I really like it.
I found the 1-8 NX8 to be a little too tight of an eyebox (moreso tighter at 1x than I’d like). But the 4-32 isn’t a problem at all for eyebox. And while I’ve never used a ZCO or “alpha” glass, I find the glass to be very good.
On the SFP NX8s, what magnification level is tied with the reticle? I’ve thought about a SFP 2.5-20 for a hunting rifle, but I know the 4-32 gets a bit dark at 32. I wouldn’t want to be tied to max magnification on an NX8 for reticle use. I like the 4-32 as a 4-20/24. I assume the 2.5-20 is best in the 2.5-15 range.
