I have quite a few portraits that would fit a lot better on those sites, portraits are not in demand on MS sites, no matter how good they are (I have just one that sells well and a dozen or so that don't). What's the average revenue? I checked a site that someone recommended a while back, to someone that didn't have a stocky port, but could sell well on those sites, I remember the site didn't take a cut at all, but as far as I could understand it you had to deal with the prints and shipping and I'm not interested in doing that, too much hassle. I'd rather give up a small percentage and leave it to them to take care of all that.
