How does the exhaust profile of methane compare to kerosene regarding soot production?

Answer

Methane burns cleaner, producing less soot than kerosene.

Methane ($ ext{CH}_4$) combined with $ ext{LOX}$ burns cleaner than kerosene, resulting in lower soot production, although it still generates $ ext{CO}_2$ due to the carbon content in the fuel.
