I hear what you are saying. The thing about skeet is it is more social, but social can get out of hand if you have a squad of guys that goof off just too much.
I've found sporting clays more social than skeet which is another reason I prefer it. I agree with Slugo on the merits of skeet. I used to shoot it often but now use it as sporting clays practice if I'm having a gun mount or other issue.
Skeet targets can be hit as well with a 20 gauge or even a 28 but should the aspiring skeet shooter discover that sporting clays is more fun then he'll definitely want a 12 gauge.
