The main difference between the two is mostly the composition of the strings, the metal being used.

Now, 80/20 bronze strings are more old school, they are really loud and bright sounding and they cut through the mix even before the amplifier is put on. The material on this string is 80% copper and 20% zinc, the steel core is hex-shaped and is wrapped by the 80/20 alloy. However, the users say it does not last long.
