constant speed or variable speed approach

Never could get a good answer on that: when is it better to do a variable speed approach or a constant speed approach.

Variable speed: you establish your approach angle and decrease your speed gradually in proportion with your distance to the pad, all the way working the collective to stay on the glide slope. Finish with very gentle leveling off. [This allows you to climb on the back of power curve super progressively]

Constant speed: establish your approach angle and keep your speed 60 knots or above as long as practicable (collective hardly requires any work because all things remain equal) finish with a solid flare and leveling off. [The later part requires you to climb on the back of power curve very quickly]

passenger comfort, risk profile, landing situation, weather, type of aircraft. what factors come into play?
