Primary advantage is that there will be no silver leaching from the plating
on components which are susceptible.
Secondary advantage is the softening of the melt point which can help with
tombstoning of 0402 and maybe even 0201 capacitors.

Primary disadvantage is the increased cost due to the silver content.  2%,
and 0.5% are two commonly seen percentages in the alloys out there in
production.
