63/37 (eutectic) is the usual replacement for 60/40 in
electronic/electrical work.

Just curious: how different is eutectic from 60/40? If eutectic is the
best, why make 60/40 at all?

Tin costs more per pound than lead. If your making tons of product per year
even the 3% differential between eutectic (63/37) and 60/40 adds up. There
are also situations where a slightly longer elastic phase might be
beneficial, compared to the almost instant "freeze" of eutectic solder
