At a glance
The 9X4 has a stiffer flex (95) and uses True's traditional T28 curve, while the PX is softer (85) with a taller blade profile in the TC4. Both are low-kick pro stock builds at the same price, so your choice comes down to whether you want extra stiffness and a familiar curve pattern or slightly easier flex with a newer blade design.
