If you're planning to install a bracket, you want that transom as light as possible, so composite is definitely worth the extra $ IMHO. A neighbor of mine that is a composites expert prefers Corecell, but he helped start the company so may be a little bias there! Maybe some of the experienced boat builders on this site like Bly or Don Herman know more about it and can chime in. Don't know how well it'll hold screws. Coosa does NOT hold screws well. For putting screws in any sort of core, I'd play it safe and drill the holes oversize, fill with thickened epoxy, then redrill and tap for machine screws, which seem to stay tight better than sheet metal or self tapping screws.
