I dont think the question is meaningless if you are talking rec tennis. I feel like certain styles may yield better results at the 4.0 and up level. This is the area when pushing gets harder to do and you have to start hitting out and setting that shot up more.
For example, attacking the backhand works at a lot of levels, and i do that myself, but relying on mistakes from the opponent and trying to open up the court more with angles is when things get a little deeper. If you hit heavy looping spin it gives time back to the opponent as opposed to risking a little more, hitting lower trajectory balls.
