OAT doesn't always wobble. Assuming you have enough spin on a disc to stabilize it, you won't see any wobble.
You can use torque to control when and how hard a disc will turn. You can also use torque to throw an overstable driver on a flat plane to keep it from hyzering out early. These are just two examples. You can use it to shape all kinds of lines - the key is you have to be in control of it. Throwing understable discs to shape lines can yield similar results, but not the same - much like throwing lefty backhand and righty sidearm.
Also, I think intentionally torquing stable discs to shape lines is more forgiving than trying to play with turn on understable plastic. That's why you don't see too many pros throwing really flippy stuff (unless they're old school players that grew up throwing understable plastic). There are, however, some lines you can only get with understable discs much like there are some lines you can only throw by torquing an overstable disc. It's good to have a grasp of both techniques.
