Best axanthic I have seen in real life was jolliff line and thats the line generally people say is the worst, 1200 grams and no brown I thought it was awesome. Each line has stunning examples and not so great examples. VPI is the most common and why I would recommend sticking with them, just more available to pick and choose from. As for one line being better than the other quality wise, Their all on par with each other imo.
