Ok, no saying one would win just because you like it better. This is a thing from a technological point of view, so phasers vs blasters, and jedi are there 2. Sith are as well. There are no rancors in the fight. No vehicles, so no AT-ATs, of AT-TEs. Land fight, and a space battle. Armies are same size in numebers, the Enterprise is in spae. So is the Executor, but it will enter at the end of the battle. 500 Star Trek capital ships +fighters and bombers, 500 Star Destroyers + TIE Fighters and Bombers. Any variations of either are allowed. Boarding is the main way to take out an enemy ship. 500,000 stormtroopers + additional speacialists of the same number. Vader is there. So is Obi-Wan Kenobi/Mace Windu. First poster picks. 500,000 Star Trek troops, and additional number of specialists (engineers and snipers, etc.) They have Kirk and Spock(he is not a pacifist here) who can use the force to the same degree as Vader and Obi-Wan, but only have vibroblades that cant be harmed by a lightsaber. They have the same powers as 1 of them.
