This is the debate over stock set wedges vs. specialty wedges.
It depends a lot on what you want your wedges to do for you. Some golfers take a basic approach and hit all their wedges square-up/straight-on with no clubface manipulation. Other golfers like more heel and toe relief so they can open the face and get more bite, go toe-down-heel-up for chip and run, or for getting out of certain turf conditions. These golfers are the ones who will get the special sole grind and bounce combinations that fit their swing best.
Take a look at the Vokey, Cleveland, and Callaway web sites it you want to see some of the varieties of wedge grinds and lofts.
Many casual golfers just go with the stock wedges from their iron set because they feel similar to the irons. Also, the set wedges usually mesh with the distance yardsticks of the numbered irons.
The GW Question
Often golf club manufacturers make at least a GW to go with the PW of an iron set. The PW and GW are the wedges most likely to be hit on full shots. The SW and LW are more likely to be used just for partial shots.
Specialty GWs have been taking a beating lately, due to the better GWs in the iron sets. At the Thanksgiving Gateway PGA sectional clearance sale, I found two brand new 50° Callaway Mack Daddy 4 GWs for $105 (retail $149). I tracked down the origin's shop rep, and he said the GWs had set on the rack for three months and no one touched them. He wanted to unload them, saying he was losing out to iron set GWs.
When testing iron sets at demo days, I have found the GW or AW to be a touchy club. Half the time the set GW is a really solid club, other times it is clunky and hard to generate any consistent shots with it.
Back in the 1970s, I played a set of MacGregor MT irons that had a 10-iron instead of a PW. The 10i was great for full shots, but sometimes hung up or dug in too quick for greenside shots. Basically, it was more iron than wedge - had almost no bounce.
