I don't expect that a gcss will ever replace my ALtendorf BUT I actually did use one the other day on a project. I was making a template for table legs that was sort of in the shape of a boomerang except the edges were straight.
Four edges four different angles. Rather than messing around on the big saw I just used the guide. Lined it up on the marks and cut,moved to the next ones and cut. At that point I didn't know or care what the exact angles were, I just knew it looked right. When I had to glue up stock for the legs of course I had to measure the angles but the guide sure made it easier and faster to cut out the template.
