I am pretty biased growing up just a few miles from the Remington Ilion factory, i even wrote my senior paper in college about Remington Arms. That being said i think the 870 has it all over the Mossberg pumps and every other pump out there. There is a reason they have sold 8 million of them, or whatever it is now, it is the pump that all others are measured against and it is just as effective now as when they came out with it. Also you can get them in a million different configurations and they are tough as nails. Like I said I'm biased, I grew up shooting remington so when i hold anything else it just "feels" wrong. But to each his own, if shooting a piece of crap mossberg makes you happy, more power to you...haha just kidding!
