Which should you choose?
The Assisted Pull-Up fixes the movement path so you can push close to failure with less skill demand. The Muscle-Up (On Vertical Bar) needs only a sturdy bar, rings or a station 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 lats adapting.
