Cycling
At least one paper behind this review states what this option was measured against. That is not a ranking, and this option carries no evidence profile of its own.

Bone Health in Endurance Athletes: Runners, Cyclists, and SwimmersEven or slightly positive pacing; faster cyclists have fewer moderate but more pronounced slowdowns
Pacing profiles and slowdown patterns in ultra-triathlon performanceComplete 500 kJ of work as quickly as possible at a freely chosen gear ratio and power output.
Effect of swimming intensity on subsequent cycling and overall triathlon performanceShorter session duration, lower work and rest times, higher number of bouts, only cycling.

A paper measuring one option against another does not make the two interchangeable, and it does not say which to choose. These are listed as what the papers did, and nothing here proposes a substitution.
