Hey, to each their own, but I have shot other disciplines, and you could cut the tension and competitiveness in the air with a knife. At the beginning to of my first CAS match, I thought the lines were a bit corny but once I let go and "Spirit of the Game" took over there was no turning back.
I enjoy this type of shooting more than any other for a few reasons; refusing to take yourself seriously relaxes you and you do shoot cooler and better, I have never shot with a safer and more considerate bunch of guys (the competition is of least import, which allows safety to be truly number one), and it is one of a very few sports where the rookie who shoots poorly has the most fun and makes the most new friends.
I get stress at work, I don't need it from my recreation too, but again, that's just me.
