A few years ago I had my vinyl - no metal guard - awning replaced with an acrylic fabric one with the metal guard.
I prefer the acrylic one. It dries faster and is easier to clean.
The only downside I have have found is that if you park under pine trees that are dropping sap it is harder to remove it from the fabric than from the non porous vinyl.
Daubing a lot of isopropyl alcohol on the sap did a good job on the sap but then had to wash the areas with detergent and water to remove the residue.
