polymaker pet-cf is fine. the differences between polymaker and bambu petcf are diminished returns
If you think it's diminishing returns to go from PM pet-cf to bambu lab pet-cf, why would you choose it over Sirayatech, which is more performant than PMs offering AND much cheaper? You can get PET-CF from ST for 37-34$/kg vs 25$/.5KG (50$/kg).

PM comes in last in every test except for Impact Resistance (which is a fail) and price (because they used the 3kg price.
The PM offering was designed with printability over performance and comes in last place in creep, 3-point bending resistance, tensile, layer adhesion (enclosed)
Where is ST Pet-cf is the cheapest tested and basically always comes in either 2nd or tied for 2nd.
