I've got a P-350 with probably 2000rounds though, and my buddy has a Benelli Nova that I've shot quite a bit as well. I'd say they are on par with each other as far as actual shooting. ****By on par I mean I hit about the same % with each gun*****
The Benelli is a nicer gun. It cycles much smoother, the bolt locks in place better, and the "goose load" button is a nice touch.
That being said, there are a few things I like much better about my P-350 vs the Nova. The P-350 is much easier to disassemble. Unscrew the end of the the magazine, and everything slides out nice and easy. The bolt is simple to disassemble, and comes out on a nice neat "try" attached to the slide. Plus the plug is simple to swap in and out, it's just a rod that sticks into the mag(5sec to put in/out).
The Nova in theory comes apart the same way, unscrew the end of the mag and everything comes out. But because the Nova has 2(not connected) rails that the bolt sits on, I find it more of a pain in the butt to get the bolt in and out. Plus the plug is a pain to take out(although this may not be an issue for you if you're just hunting).
I also personally like the slide better on the P-350, it fits my hand better than the Nova slide(just too big).
The biggest problem I have with my Nova is the bolt locking in place. Even with target loads the rotating bolt doesn't work very well. If I don't have a firm grip on the slide it will tend to open itself, which usually leads to en ejection problem. It also doesn't like to be cycled extremely quickly.
While I'm not sure I'd get another one over a Benelli (I want a new supernova!), I'm very happy with the gun. Its never given me issues that arn't very simply solved, and it was cheap, which means more $$$ for ammo.
