Why don't many people do the tomahawk/sidespin smash?

I've played against some people who are pretty good at retrieving smashes and can often lob the ball back onto the table. But I've noticed that when I do a tomahawk smash instead of a normal smash, they can almost never get it back onto the table. The sidespin is just too much for them to control.

I haven't seen many people do the tomahawk smash, not even when I watch highlights of professionals playing - they mostly do regular smashes. Why is that?

The only thing about the tomahawk smash is that the ball needs to be at a certain height (around head level) in order for me to do it, whereas I can do a regular smash from a lower height. Besides that, my consistency is probably better with the tomahawk smash than the regular smash, and I sometimes get more power out of the tomahawk smash.
