^I seriously doubt that he is, currently, stronger than Dangai Ichigo. However, I will say that if he were to go into 'Dangai Ichigo form' right now with his bankai, he will probably be way, way stronger than he was when he was first in that form. That would also imply that his Final Getsuga Tensho form would probably be stronger than when he first used it, since he has reached the height of his Soul Reaper powers, in terms of power alone.

On another note, to be honest, I think the whole of the Aizen saga was really just a fluke. Like, I honestly really thought it was such a fluke arc. I mean, almost none of the stronger captains and characters were using Bankai against Aizen. The way I see it now, I really don't see any way in which anyone can avoid Yamamoto's bankai. Or Shunsui's Bankai. Or Urahara's Bankai(will probably see it soon!). Seriously, I really do believe that, had they all used their Bankai, they would have been able to beat Aizen. And I honestly believe that they would have used Bankai if it weren't for the fact that Ichigo weakened him so much before that.
