Just, what do you think the most unique were, from greatest to least?
Mine are:
Obito
-Awakens with two-tomoe, pretty much skips third-tomoe to gain mangekyo, gains most unique dojutsu in the series, kamui, his eye's susano'o immediately appears in perfect form
Sasuke
-Perfect manipulation with Amaterasu, swiftly gains all the different powers of the mangekyo, manages to gains perfect susano'o (although EMS Itachi likely could as well, so...), awakens full rinnegan/sharinnegan (since he's shown activating and deactivating the Romeo) in his left eye (it took Madara years)
Madara
-First to Awaken Mangekyo, first to gain EMS, awakens rinnegan (the stuff he gains with the Juubi doesn't count) albeit it took him a lifetime + Hashirama's cells
Shisui
-Gains powerful mangekyo, had the unique justu "Kotoatsukami"
Itachi
-Somewhat average mangekyo, has unique genjutsu ability "Tsukuyomi"
Fugaku
-Managed to become clan leader
Fodder Uchiha
-They died
I didn't include Sarada because we don't really know her true powers yet and Indra because we don't know what his powers were either (other than the basic skill set and whether he used susano'o with or without mangekyo) and he wasn't really an Uchiha either.
