It is not really fair to compare the LV coated canvas with the Gucci normal GG fabric, which is basically not treated fabric and thus will wear over time. The comparition would be rather with the Gucci coated canvas, and they are both very similar in terms of performance and durability. I have a Gucci clutch of my mother in coated canvas from end-70s beginning-80s and the canvas looks great.
Am relieved to read this since I am thinking about the Dionysos in coated canvas and was afraid it the wear and tear would be bad.
