ideally 6v6, bracket-style- may do 5v5, but once you drop below that the meta changes a ton, the more players=the more coordination is rewarded, making the skill floor and skill ceiling higher- it'd basically just become a noob stomp if we did 4v4s
a 4v4 is pretty comparable league or counter strike tier autism, while a 6v6 or lord forgive, an 8v8, is more like a skill-based moshpit
the 5v5v5 yuru tournament strikes a very healthy balance between organization and just "lol let the other guys fight and steal their kills" but 3-way fights just run out of steam too quick to be fun, i can't see it lasting more than 2 rounds while vrc is spooling up before it starts to hemorrhage players 
6v6 is a good balance of noob friendly yet rewarding experienced players, you won't win by solo carrying through pure sweat, but you can certainly do well if the enemy is uncoordinated
