Each brand refined their marker-lines model by model. All high end guns are similar smooth shooting, efficient and user friendly. Some mid tier markers have a few features less than their high end counterpart of the same brand making them upgradeable with the better parts (different boards, asa or whatever).
I do think they did a great job with the syx as a refined version of the mini/axe line. New reg, poppet and no backcap --> more fool proof and better serviceable.
