Hi Ken,
I'm guessing that if you want to assess the texture of the canvas, your best bet would be to see it in person, if your local retailer has any of it (it doesn't seem to be in the current Epson sample books). To my eye it's got a bit more texture than the former Epson canas.
For personal work, I've been using Epson Exhibition Canvas without coating, with good results - the only thing I've experienced is that solid matte black ink areas (Epson's profiles are for MK) are vulnerable to handling damage.
I'd initially ordered the satin, but when my supplier accidentally brought in the gloss instead, I decided to try it, and found that I liked it enough to bring in several rolls of the gloss, which is not nearly so glossy as a glossy paper would be.
