Jedi had Masters, Knights, Padawans and Initiates. Consulars and Guardians were titles used by the games, they aren't actually used in the universe.Sith tended to have Darths at the top, Lords/Lady, Knights, Apprentices/Assassins and Acolytes.I'd say you'd be a Knight or a Lord.This is from my knowledge on their hierarchy anyway.

That being said, there isn't much stopping Sith Knights/Warriors from calling themselves Darth -name-. The Sith don't really have a set hierarchy and pretty much just stick to Master/Apprentice/Rule of Two, especially at this time of the Star Wars Galaxy. They're the Sith - there's pretty much no rules governing them.
