I'll give you my take on the difference between the string types, but it's only my opinion. Everybody hears strings differently, so take that FWIW. Also, I have more experience with uncoated vs. coated strings.
The names of these strings indicate the type and amount of different alloys used in their manufacture.
Phosphor bronze is probably the widest-used string in acoustic guitars. Many people say that they have a bigger bass response than, say, 80/20. I hear a more pronounced mid frequency instead. They also have more punch and volume ,imo.When they are new, I also hear a buzzy, bright kind of tone that I don't like. They're better to me after they mellow out a couple of days.The coating on some coated strings mellows this a little.
80/20's sound very different. Most people think they have less bass frequency, but some, like me, don't hear that at all. To me they are much mellower than phos. bronze, a little quieter with a well rounded sound and very even across the tonal spectrum. But IME they don't last as long as phosphors before they go dull.
As for the rest, I've nevr tried them, but I would think they too would have differences based on their composition. Hope this helps
