It is kind of a each to his own thing...and I believe several things factor in on whether to top or not to top. Such as health of the plant,strain characteristics, environment,height restrictions and grower preference ect... Here is a FastBuds Girl Scout Cookies I am finishing up,she was topped at around 15 days at the 4th node and finished up 36 inches tall and 36 inches wide. I have grown both ways, for me it just depends.
Just my 2 cents worth,
