Difference in fiberglass pool brands?

In late summer I will be getting my first pool and it will be a small fiberglass pool. I have met with some local pool builders and found one that I definitely like more than the others and he has a great reputation.

This builder installs San Juan, Barrier Reef, and Leisure fiberglass pools.

All three manufacturers have models in the size and shape I want, but the pool builder seems to be pushing me toward the Barrier Reef pool stating he feels their product is the best product. If that is the case, I wonder why the builder still sells San Juan and Leisure?

If anyone has experience with these brands, can you give me your thoughts?

If Barrier Reef makes a good product, then no worries, just wondering how they stack up against each other.

Thanks
