One major issue to contend with with fiberglass is delimitation. If water gets inside, it will separate. Stick and tin is susceptible to leaking as well, but it is easier to fix.

I'm on my third unit, and the second was fiberglass. We had a delamination issue and the entire front cap had to be changed. Thankfully it wasn't a side wall, because that would have been a much bigger issue.
