Fiberglass pools vs. others

[Pooh's Pixie]

We are considering putting in an inground pool. We did some research and thought a fiberglass pool would be a good option. Are there any disadvantages? I like the idea of a quick relatively easy installation, easy to keep clean, no liners, no torn up feet, etc. But I am wondering if I am missing something? Anything wrong with them or is there a reason to stay away?
Thanks
