Which should you choose?
The Cable Fly keeps constant tension on the muscle through the whole range of motion. The Smith Incline Bench Press fixes the bar path so you can push close to failure with less balance 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 pectorals adapting.
