If you are staying put and shooting LR, my fave was my SIII6-24... I put it on 24X and didn't change it for years of shooting. from 250yds to well over 1 mile, it was great.
But I found the 24X quite high if I was moving around and scanning for targets. I have been shooting a STAC 3-16 last summer and it did great. Much wider field of view so quicker to pick up targets and still enough mag to aim at sub MOA targets at 1450yds. Dialed back to 8 to 10X when speed of engagement was important... still plenty of mag to aim at MOA sized rocks in the sub 800yds range.
For pure LR aiming, I compete with 10-50's mag scopes so I really like high mag but for rocks and gongs, it is more important to spot your misses and see ambient conditions.
There are now variable mag scopes with a huge adjustment range so you can literally have your cake and eat it... and they come with very nice glass. I think the quality and resolution of the glass is more important then the mag value wrt to rocks and gongs shooting.
4.5-27, 4.5-29 and 4.5-30 are now off the shelf optics.
Guess you haven't mentioned if you need a low end and for what application... lots and lots of very nice optic options now.
