Is it easier or harder or about the same to achieve bent leg than straight leg? I have never seen a high school do it before I watched Friendswood HS and I think it is a cool look.
If not done properly, leads to knee and ankle issues. More difficult to do larger distance moves.
Pros to bent leg:
Natural movement of the human body. Easier to initially teach.
Cons:
Harder to clean. Varies by every individual body size and type.
It's purely up to you. You're not going to guarantee a higher area placement switching from one to the other. Uniformity and execution is more important that what your legs do. \
