Darkhunter-X...well if it just that..then yamamoto wouldn't be so impress with his zanpakuto, there are lot of single zanpakuto have greater ability than ukitake...yamamoto are impress with ukitake's and kyoraku's zanpakuto because only them in soul society hold a ability of two zanpakuto at the same time..for example, the long one of katen kyokotsu hold power of takaoni (wind) while the short one of katen kyokotsu (kyoraku most scared off) hold power of kageoni (shadow)...so i do believe that each of sogyo no kotowori hold different power whether water or lightning plus the meaning of sogyo no kotowari is the truth of pisces (twin fish)...

this is the reason why Kazeshini hisagi's zanpakuto didn't considered zanpakuto that have pair because it's actually just have one soul inside it but ukitake/kyoraku have different soul for each sword they have...plus hisagi only have one sentene/words command which is "rip" while ukitake and kyoraku is the only two that have two sentence for their zanpakuto's command since they have two different soul of zanpakuto with them...

kyoraku - "Flower Wind Rage and Flower God Roar (for katana), Heavenly Wind Rage and Heavenly Demon Sneer (for the short sword)"

ukitake - "All Waves, Rise now and Become my Shield (left sword), Lightning, Strike now and Become my Blade (right sword)"
