Reaction with Nitrous Acid and Diazonium Salts - Part 2

Which method is preferred for preparing primary amines without forming secondary or tertiary amines?

Gabriel phthalimide synthesis selectively produces primary amines by reacting phthalimide with an alkyl halide, followed by hydrolysis, avoiding mixtures of secondary and tertiary amines seen in ammonolysis.
