Decision

Which should you choose?

The Barbell Single Leg Split Squat lets you load the heaviest weights and progress in small, steady jumps. The Sissy Squat needs no equipment and scales through leverage, tempo and reps. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the quads adapting.
