Well, I just tried to search online to get a comprehensive list of the benefits of silver vs lead solder and this is what I was able to compile:

Silver is a better conductor. Meaning; less resistance, which equates to less voltage loss. Not really a huge deal until you start getting into the higher currents where you start getting more voltage losses. If pulling 100A through a contact resistance of 0.001 ohm, 0.1v is lost. Ohms law, that's all.
More environmentally friendly. You don't want to ingest it (duh). Lead is bad, nuff said. :)
Silver has a higher melting point. This is good and bad. Good because it means it won't melt as easily if there is a ton of current - bad because it's harder to solder.
Silver solder is generally more expensive.
