I would have a hard time fitting myself into any of those catagories. I love the competition, and I seriously try to win. But at the same time, I don't try to buy a win. I get a bigger kick out of using a bone stock gun, not because it is more realistic but because I never get serious enough about any one of the sports to jump through all the custom gun hoops. I also like to keep in the spirt of the particular game, for example in IDPA I shoot a legal gun from concealment; a rig that I could (but don't) actually carry. I don't really carry, so I just pulled a gun out of the safe that I seldom shoot and decided to use it just because I have it and now found a good use for it. I have tried a number of the shooting sports; IDPA, IPSC, bowling pins, small bore silhouette, some vintage military rifle matches, trap, sporting clays etc. I feel that my participation in them improved my overall shooting greatly. The fact that they are a game doesn't detract from this in any way. I find competition a whole lot of fun. I enjoy it no matter how good or bad I do, and have never spent a lot of money on any of it.
As a side bar, I was thinking about this the other day. As I mentioned, I dabble in various shooting sports. My work schedule doesn't allow me to get real serious about any of them because I can only make maybe half the local matches. Since I can't make most of the matches, I tend to lose interest and shoot whatever I can. Anyway, I have noticed that I usually do great the first time I show up. I have even either won or placed in the top couple people in my first match. Then as I become enthused about it; read about it, start worrying about my equipment and loads, I tend to do worse or not improve. There is something about that first time that brings out the best in me, then I try to out-think myself. Try to get into too many gimmicks.......... I just found that interesting and wondered if anyone else had this same experience.
