Short answer:
PolyLite™ PLA is a very rigid material with very low impact resistance.
PolyMax™ PLA is an extremely ductile material with high impact resistance and durability.
PolyLite™ PLA Pro is the best of both worlds combining excellent rigidity and high impact strength.

Long answer in the Polymaker live experiment here.

As you may know regular silk PLA has different mechanical properties as regular PLA, however with PLA Pro we developed a technology to have the silk and smooth finish without affecting the mechanical properties. PolyLite™ PLA Pro Silver has the same high impact strength and rigidity as the regular colors but with a much smoother and silkier surface finish.
