If you will be parking under trees I would say the vinyl is preferred, regardless of brand. Vinyl can be cleaned much more easily than any woven fabric. Tree sap in particular gets right down in the weave, whereas it just sits on top of vinyl. [By the way, use alcohol to remove pine pitch (sap).] Vinyl can be scrubbed, bleached, scoured and scraped as needed to get off dirt, grime, sap and such. Woven fabrics must be treated somewhat more gently and can be darn near impossile to get grime out of the weave. And if you use really strong cleaners or lots of bleach you may have to re-waterprrof the fabric. It is not inherently waterprrof like vinyl.
But the woven fabrics are lighter and often prettier (more subtle color variations, etc.)
