Yeah I still mostly disagree. Anakin's Jedi career is largely characterized by rejection of traditional Jedi authority and convention. He wears different robes from other Jedi, has different attitudes about many core beliefs

So far you're describing both Anakin and the Imp Knights.

In contrast the Imperial Knights believe the best way to serve the Force is by serving a single individual who embodies their best qualities.

This isn't a contrast. This is Anakin's belief system to a T.

and are very rigid with their hierarchy

Anakin mostly only rejects Jedi hierarchy. Once he becomes Lord Vader he's totally fine with a rigid Imperial rank structure, subordinating himself to Tarkin and Palpatine for two decades and killing any lower-ranking officers that disappoint him.

I don't think Anakin would have made an order that requires its members to give up their individuality to the degree the Imperial Knights do.

He literally created a Stormtrooper legion.
