For me the Eighth has the best design out of any of the inquisitors. Even though the Seventh Sister is my favorite inquisitor I have a little head cannon that says that Eighth lived from the fall. Force senitives are known to fall extreme heights and jump up extreme hights too. Added to my fan theory he is a terrelian jango jumper which its in their name they are very acrobatic and can jump high. He doesn't have the bulkiest or most ornate armor design but is simply but effective. Don't even get me started on his lightsaber, it may look simply but hides a rather intimidating feature. He can eject numerous sharp blades from his hilt and use it for an intimidation technique.
