1.5 & 1.6 Rocker ratios - What's the diff??

What factors need to be considered when deciding on installing 1.5 vs. 1.6 ratio rocker arms?

I'm starting to but parts for an engine build and can't seem to figure this one out?

If you have to ask this question you don't need to worry about Rocker ratio. More area in applications where it's needed.
