It's just different, tends to be more anteriorly loaded than a normal back squat (which is more posteriorly loaded) and allow pushing legs more than a front squat (upper back usually fails before legs in a front squat).
I am doing them because I am transitioning into strongman where a lot of events need more anterior strength, vs where I was powerlifting before and happy to do everything in a very posterior chain heavy way.
