Leaded is objectively better for everything except health/pollution. Which is the point of RoHS.
Leaded solder has a lower melting point, flows much better, easier to visually see bad solder joints, and doesn’t form whiskers. Also less brittle, so cracked joints are less likely.
Fumes don’t contain lead, it’s not nearly hot enough. Those fumes are flux burning.
