Their both excellent choices. If you are left handed, the BPS would probably be the better choice since it ejects out of the bottom. The left handed 870's are hard to find. I only say this because I am a lefty and have 2 left handed 870's. I've shot the BPS and think it is a great gun. It is however more expensive than the 870 express and I think a little cheaper than the 870 wingmaster.
