It’s ironic because I have the opposite experience. Stretched canvas tends to weaken and slump on the stretchers, gets punctured…no thanks! I like panels because of their durability, and art conservators definitely recommend rigid supports.
I think canvas glued to wood (or rigid support, like Gatorboard) is a good compromise, because you still get that glorious canvasy texture, but the board isn’t vulnerable to punctures the way stretched canvas is.
The only time I’d consider using stretched canvas these days is if I was painting something very large that was too heavy with a wooden panel.
Found a link with an interview with the guy who ran AMIEN (who sadly, has since passed away), the art conservation forum. : Painting: You’re Doing it Wrong
#5: “The number one thing you can do as a painter to help ensure the durability of your paintings is to paint on a rigid support, like a wooden panel. If you prefer the texture of canvas, you can mount it to a rigid support instead of stretching it. “A lot of people don’t like to hear that because it makes a very heavy support,” said Gottsegen. “But if you’re going to paint with oil paint, then [the canvas] ought to be stretched on a panel, not loose.”
