Alright I was just going over characters Zanpaktou's and I realized something odd in my opinion. The Tassels that a few Shinigami have on their Zanpaktou or take on a different appearance in their sealed form (other than a sword and sheath). Seem to be the most powerful of the Zanpaktou. Such as
Ichigo's Zanpaktou (Zangetsu) in its sealed, shikai and Bankai all have something on the end of the hilt and handle. A tassel when it was sealed (can't find a good pic showing it)
his shikai:
Notice the cloth at the end of the handle
His Bankai:
notice the broken links at the end of the handle
Isshin Kurosaki with only the hilt and handle being shown of his Zanpaktou it also shows what Ichigo's sealed zanpaktou had which is the tassel:
notice the tassel at the end of the handle
Kisuke Urahara's Zanpaktou (Benihime) in its sealed form appears to be nothing but a cane (the blade on the inside) and in its Shikai:
Notice the Tassel on the end of the handle
Shigekuni Yamamoto-Genryuusai's Zanpaktou (Ryuujin Jakka) In its sealed form is a stick (walking stick to be precise):
Shunsui Kyouraku's Zanpaktou (Katen Kyōkotsu) Alone in it's sealed form is two separate zanpaktou's and in its shikai they have tassels
Notice two SEALED zanpaktou (the only kind like that)
Notice the incredibly large tassels and dual zanpaktou
Toushiro Hitsugaya's Zanpaktou (Hyourinmaru) In its sealed form is too large for him to carry on the waist so he carries it on his back. But in its Shikai it has a chain and crescent blade attached to the handle
(you cant really see it in this pic though but it is there he has used it in his fights)
Kenpachi Zaraki's Zanpaktou being the only other Zanpaktou to be in its Shikai state permanently it yet has a tassel (cloth) at the end of its handle:
Its tiny but still there
Juushirou Ukitake's Zanpaktou (Sougyo no Kotowari) in its sealed form isn't anything special but in its Shikai is connected by a cloth with tags hanging off it.
Note also being a Dual Blade Zanpaktou as well
Shuuhei Hisagi's Zanpaktou (Kazeshini) As well in its sealed form isn't too special but in its Shikai its connected buy an extremely long chain.
Note as well as being the third only Dual Zanpaktou
Ikkaku Madarame's Zanpaktou (Houzukimaru) Also in its sealed form isn't anything special other than having a healing ointment in its handle. But in its Shikai it has a tiny red tassel and in its Bankai it has a chain connecting it.
His Shikai:
Notice the tassel
His Bankai:
Notice the large chains and the tassels for a hilt.
Rukia Kuchiki's Zanpaktou (Sode no Shirayuki) In its Shikai has a very long white cloth at the end of it
I believe these are the Strongest of the Zanpaktou in the series due to the fact that about 75% of the ones I listed have yet to be shown in Bankai.
