The Tl;dr is that more silver means a lot better mechanical strength, slightly worse shock strength, and better wetting of the joint. High-Ag (>=3%) alloys can produce deformed joints during cooling because of a "platelet formation" process, which requres precise T control during automated reflow soldering. Small amounts of Bismuth make the joint look nicer.
