I had a couple of them that I used last year. Alas, I never had a shot over 100 yds. I love the size of the scope (almost perfect for a 40mm scope) and with 5" of eye relief, you're not going to get a scope cut unless you try to. Glass was great too, all in all, I think that for under $250, it's hard to beat it.
I didn't care for the circles, they seemed to clutter the FOV a bit more than I liked. I also hardly ever used them, I'm too used to sighting in a couple of inches high to compensate for longer range. I like the Burris Ballistic plex with it's dashes better than the circles, but that's just me.
I think that the Omega with the regular x-hair would be my choice for a 3-9x40 scope that would be on any rifle with decent recoil, until you get into the dangerous game calibers.
