Which should you choose?
The Barbell Overhead Squat lets you load the heaviest weights and progress in small, steady jumps. The Bosu Ball Squat adds an unstable surface that raises core demand. 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.
