I don't think correlations between GT and Z can be made properly anymore. There are many contradictions, not the least of which is Bills remarking that Goku couldn't beat Frieza short of his SSJ1 form, yet GT having him defeat both Frieza and the even stronger Cell in his Kid base which wasn't even as strong as his normal base.
The difference is that Sasuke only had the Mangekyou in one eye if I recall or at least was limited to amatserasu and very limted Tsukiyomi. He now has the Eternal Mangekyou in both eyes and can seemingly spam all the above to a much higher level. Note, he did not even have Susanoo when he fought Bee and that's arguably his strongest power as well as his greatest defense by far.
Love how this turned into who would Goku do and who we would pick. Oh well I'll join in! I'd give Yoruichi the slight edge also but why not get Soifon either? Lol. Still like Nel over the both of them however.
