I had zippered canvas on my 15 with no problems, but I never did need to remove the canvas.I would think that it might be nice to have that option, should you need it, though I don't think Sunbrella recommends using a washing machine for your canvas!
The nice thing about this is that you can remove the canvas to re-attach buttons/snaps if necessary, or do any sewing/mending that might eventually be necessary, without having to remove the frame from the boat.
If it is not an up-charge in price, I'd go with the zippers personally.
If you store the boat for long periods, you can remove the canvas and store it in your basement/indoors with your cushions, etc; rather than exposed to any water/rodents or other potential problems during storage.
