well I see your point but I would still choose the Theron Sentinel fore they are by far the most elite soldier bred in the Hollow and theres a reason for that. I know Jedi are trained from a very young age but the Sentinels are trained from BIRTH. they do not play, they do not love, they do not have any sort of childhood their lives are consumed with the art of leading and killing. and I would imagine they are of a decent adult age so all thats left are cold calculating and vicious warriors.
Sith Marauders are fiercely independent loyal to only themselves and Marauders are not Sith masters and as such really dont put their force powers on priority. They excel only in lightsaber combat using mainly force crush and maybe force lightning.
Theron Sentinels have legions under their command including lesser Theron guards
They also have the power to call in living tanks aka "Brumaks"
They are incredibly dangerous by themselves using their torque bows to a lethal and accurate effect.
and plus I find that it never gets old when you kill someone and they utter "diiieee sssapien"
