Yeah, it is often the question to what level simplicity should be preferred over flexibility.

When you go with the specific texture names, you wont be able to reuse the same texture for collidable and non collidable objects (won't be able to disable collisions).

I like the groups idea, as it is very flexible. And it worked very well in Blender 2.4x. It just got a bit less intuitive in 2.6x, with this weird restriction that you have to select an object to add other objects to an existing group.
