Phosphor Bronze vs 80/20 Bronze Acoustic Strings

Verdict at a glance: Phosphor bronze for a rich, full, warmer voice that settles in (the beginner default, and what most acoustics ship with); 80/20 bronze for a brighter, livelier attack - lovely on a dark-sounding guitar, and it mellows faster uncoated. Coated versions of either (Elixir below) stretch the timeline.

FAQ

Which lasts longer?

Uncoated, phosphor bronze generally keeps its character longer; coating matters more than alloy for lifespan - see coated vs uncoated.
