+1 on the BPS. It was my first shotgun not too long ago.
Better action than the others, no question. Something I didn't think about until I fired it was the ejection difference. It's a little thing, but not having that shell zinging through your vision (it's a bottom eject) really helps with acquisition of the next target.
The smooth action means that it doesn't affect your swing nearly as much when you have to pump for repeat shots. I won't get technical as to why, but the muzzle rise when firing is noticeably less than it's competitors.
What this all means is the gun is not fighting you while you're learning to use it. As a noob this all turned out to be very important to me.
