PPA-CF vs PA6-CF?

Does anyone have experience printing PPA-CF and PA6-CF? I had read that “PPA-CF is 48% stronger” than PA6 if you get good layer adhesion, but I’m seeing conflicting info regarding impact resistance. Anyone have input who’s printed and used both?

    PPA-CF if you can print above 300c. Siraya Tech Fibreheart PPA-CF is some good stuff and not that expensive, around $60 for 1kg. I’ve had really good experience with this so far.

      they have a 45$ variant if you are printing .6mm and above. Has a larger nominal cf fiber length. This version will NOT be restocked as it was an upstream supply mistake. I have tested it down to .4 without issues, buy YMMV.

      Also, within a month they will release PPA-GF which I expect to be the best value for performance filaments in our space. 45$ at launch, dropping to sale price around 38$
