Higher Mass is only a positive if you are aiming at lower compliance cartridge designs....It is higher mass - which I prefer - the magnetic anti-skate has the ability to disengage without changing its setting, the VTA lifter range is 9 mm versus 6 mm in the Technics, and the overall construction appears more robust (from images versus touching).
My preferred cartridges have always been high to very high compliance - with optimum arm masses being in the 4g to 6g range
The technics arms are mid-mass designs - typically around 12g... they work OK with high compliance cartridges if fitted with an oil damper.... otherwise it can get tricky.
