Hail damage on aluminum is easily repaired...and not nearly as costly.
Hail damage on fiberglass (FRP actually) is very expensive to repair, many times it will cause your whole unit to be totaled..
Aluminum is mechanically hung onto a wood substrate and wood studs. Fiberglass is glued to substrate and metal studs. Damage an area on fiberglass you most likely will need to replace the whole side / end panel. In Aluminum you can repair/replace individual sheets.
To each their own, both have plus's and minus's..
