So shopping for Polymaker PLA and trying to figure out the differences. Here is what I think they are?
PolyTerra - Matte finish??
PolyTerra + - stronger still matte???
PLA - regular gloss Pla???
PLA Pro - Strongest??
Are these the differences or am I missing something?

PolyLite PLA is high rigidity and high stiffness but brittle
PolyTerra PLA is softer, easier to sand, easier to remove supports. But equality means it will wear faster and break in z axis easier. Definitely good for fun or aesthetic models needing the finish
PolyTerra PLA+ is strength optimised version of PolyTerra formula, so still less stiff than PolyLite, less tensile strength but better impact resistance and ductility.
PolyLite PLA Pro maintains most of the strength and stiffness of the PolyLite PLA but significantly improves toughness and impact strength.
PolyMax PLA is less stiff, similar stiffness to ABS but has the best ductility and impact strength. It's a great replacement to ABS in mechanical properties
So for best stiffness or tensile strength go PolyLite PLA. If you also need impact resistance go PLA Pro.
If you like the satin finish or a combination of good price and mechanical properties go PolyTerra PLA+
If you love colour range and matte finish or want easier support removal go PolyTerra PLA.
If you want the most durable PLA, go PolyMax PLA.

All PLA warp under basically any stress over time and lose integrity suddenly at 55C so no PLA replaces ABS. If you are working only at room temperature and the applied stresses are not continuous, then it can work.
