Lead poisoning risks aside, Melting temperature is the main difference. Leaded solder is much easier to work with as the melting point is lower, and the temperature window to allow you to work the joint is wider. Unleaded solder just seems to be solid, then molten for a few seconds, then instantly solid again once heat is removed. It's horrible to work with, but more suited to automated flow soldering of circuit boards.

I only use leaded solder
