I didn't think anyone was even getting the non-high cut ones for club gymnastics anymore.
The traditional cut doesn't fit any better from my point of view (and looks worse). They'll still ride up. We had some for high school gym, was terrible. I've had high cut leos that stayed so much better and the fit was so much more flattering. The greatest influencing factor of that is the fit of the leo and the fabric type. Some of the fabrics tend to be looser/stretchier and ride up more. The more common mystique or dot mystique fabrics that have a tighter stretch to them tend to stay pretty well.
After a certain age I find that pretty much any and every long sleeved leo will ride up during the course of a floor routine (sleeveless do a little better here because they don't ride up as soon as you lift your arms). It's just a matter of getting a decent enough fit that not too much is exposed.
Also the sizing leos that are sent aren't that useful in my experience. They're often stretched out and nylon fabric that is stretchier than the fabrics that are favored today.
If you have a gymnast with a long torso, and are concerned about fit from that standpoint, then the long torso option is the way to go in my opinion over traditional leg cut.
Edit: reading that over, I had no idea I such intense and specific feelings about leg cut on leos.
