I've had the Delta Styker, Athlon Cronus BTR. Delta is one step up in optics quality than the Cronus . The Leupold is one small step above the Delta. I didn't like the reticle in the Delta. Just for comparison, I have a Nightforce ATACR 7-35x56mm with great optics, but overpriced. BUT I recently picked up a Sightron SVlll 5-40x56mm FFP from Liberty optics in MT for $1699.00 and its optics quality is equivalent to the Nightforce at half the price. Thumbs up to the Sightron
