That's a tough question to answer since we're talking about not only a different reinforcement material (linen and canvass vs. glass cloth sheets) but resin system too.
It's a different composite altogether.
But if we're talking gripiness, ofcourse it depends on how fine or rough the material was finished, but I will say it's more similar to linen micarta. It's pretty fine and slick. But again, it depends on how it was finished.
