Information is so good and useful. Plywood might be more resistant to beating on rocks. Aside from that, stitch and glue requires plans or a pattern or some experience in developing patterns for cutting out the plywood. After that it's a bunch of fiber glassing, sanding and varnishing. That might be enjoyable but I don't know since I've never tried it. Skin on frame designs can be modified on the fly since you fit each new piece to what is already there. Very little detailed design work is required. Also very little epoxy and sanding.
