Not really, in that scenario it was Teach with his full crew, and Akainu by himself with some fodder.
Here GB is dealing with an alliance which is factually > 2 Yonkou Captains + 1 Yonkou crew, and now he has another Yonkou crew pincering him.
Mind you he is doing this all against Akainu's orders. He was already being pretty stupid waltzing in on the alliance, but if he didn't back off after discovering Shanks and crew were on the borders, he'd be the second most retarded character in the entire series only behind Oden.
