I prefer wood tees because they tend to crack before they malform. That way, I know for sure when to retire one. From observation, the Stinger tees seem more durable than the common stock of plain wood tees. I also believe that they offer a little less resistence to the leading edge of clubfaces than other wood tees. On an last note, they are also perfectly symetrical no matter which way they are rotated in the ground. I feel as though a tee that is not that way may produce an improper trajectory bias.

I have never seen a significant positive change from a tee to my ball fight beyond that of using the common type. I still like to think I have an advantage with my special choice of tees, though. The only thing I have noted that can clearly improve on a wood tee is how far it is has to be poked into the ground. In my experience, between a really long tee and a really short tee that hold the ball up the same distance from the ground, the short tee feels better and seems to fly with a better trajectory.

A common, normal-size headed, wood tee that is just the right length to stay in the ground seems to currently satisfy me. A person can take a normal tee and shorten it with a pencil sharpener to get just the right length required. I buy Accuity brand 1 3/8'' tees for using with almost every club. I use the common 2 1/8'' tee with the rest. Pencil sharpening a bunch of tees hurts my fingers.
