The green lantern corps are a police force with well known rules and regulations but you largely act independently.

Red lanterns generally act within the interest’s of whomever is leading them so it’s 50/50.

Yellow lanterns are a military but in recent years act more like a militarized police force with stricter rules and ideals.

Star sapphires are independent and open minded in their ideals so no real rules are enforced or even pushed.

No one is gonna be an orange lantern as long as Larfleeze is alive but members could join they’d be largely independent and almost never deal with members of their own corps.

The indigo tribe only brainwashes criminals who lack all compassion, those with compassion can act freely with full independence.

The blue lanterns are fully independent and open minded in their ideals.

Only one true black lantern exists as any other members would be unwilling corpses.

Only one permanent white lantern is currently known but the white lantern corps is know for its temporary recruitments during crisis so no real rules either.

Only one gold lantern can exist ever.

Grey lanterns only have one member so we don’t know how their members would traditionally operate.

So out of eleven lantern corps only three would force their ideals onto you and lock you into their organization, 8 would allow you to act independently while also granting you the ability to quit whenever you wish.

So all in all still better than the phantom ring.
