Carver, word of advice, until I leave the site or am banned, refrain from making statements about anime/manga vs. comics, because while I am hardly the most knowledgable comic guy on the site, I know more than enough about manga and anime to refute any of your claims, and you know this better than I do.
Let me start with the SOOPER BLADE BLOCKING FEAT.
First of all... Where the **** did you pull a "billion" from?
Byakuya's Zanpakuto is referred to as Senbonzakura, which translates to Thousand Cherry Blossoms. The blossoms in question being the "blades" he attacks with. You have no basis to claim a billion blades.
This is the feat in question:

Considering how many of the blades there are, their size, and the size of Ichigo's sword, it would be impossible for him to have swung once for every individual blade, he blocked many blades with each swing.
Beyond that, we don't know how fast they were going. To use this feat as basis for claiming he is above Diana in speed is idiotic.
Don't even get me started on the whole "Ichigo can physically restrain her" bullshit...
