But the problem is you have no proof how much stronger hiruzen is... How much he is capable of its just you guessing he could have been just abit faster and had abit more stamina and chakra ...
You also don't know how much stronger hashirama is (current hashirama Edo) who is showing op techs sm ect hiruzen has nothing on him unless you can tell me what he can even do to hurt hashirama ? And that Edo is still not at full power
And the oro thing .... Just before hiruzen used it Orochimaru said 'Show it to me' what else does that mean the same fight you link watch it and you will see
I guess you're the type of person who says Sakura > sasori and sm Naruto > pain right ?
Btw your arguement also works against you what proof is there that prime hiruzen could beat any current top 5 ?
Minato in that position could have done the same and ended up sealing Orochimaru along with him
And only reason is because you're using that fight to try say say hiruzen > hashirama and Tobirama
Let me guess hiruzen also beats kabuto ,madara,bm Naruto,ems sasuke,nagato,obito aswell? Hell this prime hiruzen also beats sage of six paths since he is so strong He doesn't exist , there is absolutely no information on him besides him being better than is older self other than that that hiruzen is pure speculation as you say... For all we know ems madara could beat prime hiruzen ( I am not saying he can sice I don't know how strong hiruzen is)
Please though carry on believing hiruzen is untouchable ill just tell you with his current feats even tsunade shits on him
You seem to know how strong this prime is though please tell me so i don't underrate him
