I think you all need to go back and read/watch that section of bleach again. Aizen doesn't truly admit it, but even he realizes that Ichigo became more powerful than him. Here is Azien's internal monologue when he sees Ichigo's final form, "As long as I do not purposefully lower my level and interference, neither humans nor shinigami should be able to feel my reiatsu... Are you telling me that he is standing in an even higher dimension?" When his zanpakuto starts to disappear, but before Urahara disillusions him, he says, "Just like you who have become one with your zanpakuto and its powers." So even Aizen admits that Ichigo was more powerful than him. Furthermore the Hogyoku rejects him as its master, because it recognized that Ichigo defeated him. The FGT managed to split Aizen in half and dissolve his final form. Aizen's ultimate attack only managed to burn Ichigo's arm.

The bottom line is that Aizen was defeated. He wasn't even defeated by Urahara. Aizen was defeated by Ichigo. You may not like it, but the deciding factor in this debate is the Hogyoku, not you. The Hogyoku did not restore Aizen's powers, or bring his to a new level, hence it has determined that Ichigo won the fight.
