Both would work just fine, any 12 gauge and you really cant go wrong. I would prefer a pump, generally cheaper, equally as effective, and if something goes awry a pump is much easier and generally quicker to fix and be ready to fire. Honestly though with either well maintained and in your house and if you EVER needed to fire a shot, it will most likely be only one and your chances of having a problem at that exact point in time are slim to none if you take care of it and know propper cleaning, maintenance, and how to clear a jam or fix a problem, you will be fine with either. Pick what you like. My personal choice is my Remington 870 tactical. Ext. magazine tube, ghost sights, recoil reducing pistol grip stock with a side saddle with any choice of shells on it. Best for me, but not everyone.
