I chooose no simply because
1.harashima has a kekkei genkai
2.at a point had several bijuu in his possession
3.defeated madara although mada used the kyubi
4.taught the 3rd
while minato is
1.has ftg
2.rasengan
And yes smart but arent all kages my question is
IS MINATO STRONGER THAN HARASHIMA?
minato is stronger, why?
1.one of the fastest ninja in narutoverse (when it comes to a battle between skilled shinobi's speed ALWAYS wins)
2.it has been stated many times 4th was unrivaled
3. the say many times the next generation surpasses the previous by that theory 2nd>1st>3rd>4th (u could argue tsunade..but she was chosed by default)
...now to ur points yes 1st had wood KG, n thats is the reason he was able to supress the tailed beasts so that really isnt a measure of strength.
we dont know what type of powers madara had...so far he hasnt shown anyt of the MS abilities (if tobi reali is madara). also madara and 1st were rivals, i.e equal grounds...as far as we know minato had no rivals meaning no1 could keep up with him.
as far as feats, again yes 1st has wood element but 4th had his own jutsus as well..ftg, rasengan, drs
