I have shot one, and it's simply an 1100 with different features. That is not a bad thing to me, as I am a 50 year 1100 fan. I have owned 12 of them, and carried one from here to Canada, and I won't own an unreliable gun. An 1100 won't run as long between cleanings as some of the newer gas systems, but several hundred rounds is no problem, and then you do not need anything but a quick spray and wipe of the gas system parts; 5 minutes tops. The Benelli has lots of proponents too, and they work fine, I just don't like inertia actions. The Benelli is very reliable with the right loads, and it has to be backed up to function properly. These two seem to be the most popular platforms I have seen in 3 gun.
For "home defense" or blasting cans and watermelons either is way more than up to the task.
