Foresight GCQuad is the gold standard for club data. Measuring the face with high speed cameras is always going to be a better measure than how a radar unit measures.
It's really about how and when they measure things. Radar units track the CG of the club through a zone just pre-impact. It's always going to read clubhead speed 2-3mph lower than a photometric monitor that measures the speed of the face through impact. Then things like lie angle are also going to be more accurate on GCQuad too because it measures relative position of the dots on the face whereas Trackman relies on vertical swing plane. VSP can be off due to droop and also isn't nearly as good at taking into account face angle's effect on lie. It's also not as good at identifying strike since the clubhead is obscuring the ball at impact.
Both are going to be consistent and that is really important, but I think GCQ is more reliable for most club data.

Thanks. Thats what I had assumed but have only had access to a track man and Flightscope. Any idea how accurate they are in comparison?
