Team Luke SkywalkervsTeam Darth Vader

Team Luke Skywalker As all characters are from canon it's so ez to define the winner team.
Luke vs Vader*
Anakin vs Palpatine*
Obi-wan* vs Maul
Yoda* vs count Dooku
Mace Windu* vs Kylo ren
Rey vs General Grievous* (Debatable)
Ahsoka & Qui-gon* vs Asajj ventress
Yoda, Windu, Obi-wan, Ahsoka and Qui-gon > Darth vader & Palpatine
So light side wins

Team Luke Skywalker I mean... Luke solos Kylo
Anakin solos Dooku
Mace solos Palpy
Obi Solos Grievous
Yoda Solos Vader
Ahsoka solos Ventress
Which leaves Rey and Qui-Gon vs Maul

The question is can Rey sub in for Obi-Wan in the phantom Menace?... ... I think so, she'd get stomped in lightsaber combat but if she uses the force she'd stomp... hmmm... anyway, if this is neutral ground there is no reason to think Qui-Gon would be left alone with Maul like in TPM, so I'd give them the fight, if not well they'd last long enough until Anakin finished Dooku or Luke finished Kylo and come to help, Qui-Gon lasted a solid 20 minutes in TPM, doubt Kylo would last as long against Luke and Anakin vs Dooku lasted 2 minutes.

So Team skywalker has got this in the bag.

Team Darth Vader Depends. If It's Expanded Universe I think Grievous can deal with everyone here other than Mace and Yoda.

Team Luke Skywalker Why does the light side get a extra of hero's.

Anakin Skywalker* vs. Asajj Ventress
