Which should you choose?
The Barbell Bench Squat lets you load the heaviest weights and progress in small, steady jumps. The Dumbbell Single Leg Split Squat works each side independently and demands more stabilizer control. 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.
