"which Lucent would win in a fight" RDM!Lucent by a malm, on account of a much larger percentage of his education being fights, and also a much larger percentage of his daily routine being fights. SGE!Lucent is still hard to kill and not a force to antagonize lightly, but he has fewer options if you get close, and on the whole he does not hit as hard as "very angry magic swordsperson barreling towards you, very very angry"
that being said: SGE!Lucent rolls better on intimidate checks.
