I haven't spent time at the Four Seasons facilities, but Sheraton is nice--probably the best beach location. Intercon has a good beach but they get A LOT of day-trippers who can overrun the place at times. Also lots of Western corporate parties, which can takeover too. This attracts young Arab men looking to ogle women in bikinis which makes the place even worse. Good friends cancelled their membership after being frustrated by all of this--they just wanted a low-key place to workout and relax.

I'm at the Diplomatic Club, but I get the membership through work. I probably wouldn't select it if I were paying. It's increasingly where Qataris go to drink which is a good or bad thing depending on your perspective. The facilities are decent, but I wouldn't call it much of a family hang-out place.
