Nah I'd go with Hollow Ichigo giving him trouble, and I thought Ichigo only truly bet his hollow during his Vizard training. And that was only because he just stood there dumbfounded for god knows why.

From what we've seen he's stronger, faster, more creative with how he fights and his Getsuga Tenshou makes a bigger boom. And thats ONLY inside Ichigo's soul where he only falls back on his shinigami abilities and taunting.

Think, if he were to use hollow abilities + shinigami abilities + actually trying, Aizen would lose. I'm not saying it'd be an easy fight or anything (cause that would just be boring) but in the end I think Aizen would be overwhelmed.

Course this is only speculation on a topic this blog doesn't address, maybe someone could make a blog on people's thoughts of Hollow Ichigo's role in things so people could discuss this freely.
