I don't own a Swarovski, but I do own another $1,000+ scope - Nightforce. I won't recommend the Nightforce over the Swarovski for your CDL in 280, but I'm not sure that the Swaro A is the right choice either.
I have shot rifles with Swarovski scopes, both the American series and the PH series. IMHO, the PH series seemed to have better optics, but not by much. The PH series are usually 30mm main tubes, while the A series have the 1" tube. The PH has little eye relief, while the A series has a bit more (around 3.5")
Actually, I think that the optics of the Nikon Monarch are close to, but not better than, the Swarovski A series. How close is the Monarch optically speaking to the Swaro A? Close enough to justify me not spending 3 times the money, but that's just my opinion.
As was initially stated, if money is taken out of the issue, then the Swarovski is the better scope of the two.
