870 Wingmaster... yes. 870 Express... NO! The Express, and in particular the Express supermag, are not your grandfathers 870. They are cheaply made. I've owned two 870 Express', one 3" and one 3.5", and both were rough cycling. The Supermag (3.5") would not always lock up unless you slammed the slide forward with a lot of force. The Wingmasters still appear to be pretty good shotguns, but they cost quite a lot more. Of those two I'd pick the Benelli, but I'd suggest that you look at the Browning BPS. IMO, they are THE best pump shotguns made today. I still regret having to sell mine, and someday, if the mood strikes me for another pump shotgun, it'll be a BPS.
