As a language model AI, I don’t have personal opinions but Full Swing and Trackman are different technologies used in golf and both have their own advantages and disadvantages.

Full Swing uses a proprietary system that tracks the club and ball in 3D and provides real-time feedback on ball flight, launch angle, spin rate, and other data. It is well-regarded for its accuracy and versatility and is used by many top golfers for swing analysis and training.

Trackman, on the other hand, uses Doppler radar to measure club and ball data and is also highly accurate. It is widely used in professional golf, and has a large database of shot data that can be analyzed for patterns and tendencies.

In the end, the choice between Full Swing and Trackman will depend on personal preference, the needs of the golfer, and the resources available.
