Comparing pebble sizes offered by different companies

I'm planning a pool build, and we've chosen a builder that prefers WetEdge products. I'm trying to compare the WetEdge offerings to NPT, Pebbletec, Finest Finish (Premier Pools uses them) and am having some trouble. For example, I've seen the Micro Fusion by Finest Finish and liked it, but am unsure how it compares to others in terms of size.

Does anyone have a good comparison of different pebble sizes offered by different companies, and how they line up with each other?

Thanks!
