Aluminum vs. Fiberglass

Hey all,
I perused previous threads about this but didn't quite get the answer I was looking for, so I thought I'd start a new thread.
I am a soon-to-be first-time teardrop owner, and I know next to nothing about maintenance and that kind of thing. My builder recommends a fiberglass skin because it is less likely to come away from the wood underneath after extreme temps, and I won't have to worry about leaks. But I really like the look of aluminum skin, way better than fiberglass. Do you think that checking for leaks (and fixing them) on an aluminum-skinned tear will be easy for someone who hasn't any experience with that kind of thing? Or do you recommend I just go with the fiberglass?
Thank you!
