The pricier one is lead free.

Those are vacuum breakers. If you have a steady flow of water, and want a true back flow preventer, this is the way to go.

This is the one that isn't lead free. The lead free is usually about $10 more.

Might be helpful to know the intended use.

I heard (but not verified) that local code requires these to be used on the outside spigot when attaching a garden hose. I have one, I need a second one.

I'm surprised they even make one with lead. Your never wrong going on the assumption that people are stupid and every water spigot will potentially be used for potable water.

I can see a lawsuit in assuming otherwise.

A small amount of lead in a brass alloy improves its machinability. The percentage is less than 2%, and after a short period of use little leaches out of the brass. Old lead solder where it is exposed in a joint is a much greater contributor to lead leaching into water.
