i asked my cousin the same question 1st vs 4th and he said 4th i dunt knw why but for me i like them both alot,now the 4th hokage those who r saying he has only shown his FTG technique and he would lose to the 1st cause of his forest and darkness, well first maybe he only uses his FTG technique maybe cause he doesnt need anything else,when the 4th saved the village he had to save his son,wife,village,fight madara/tobi and he also teleported the 9 tails somewhere else 2 seal it,he took out an army i believe in about a 1min,and dont forget he did have the title of Hokage at a very young age,now for the 1st yes he is a truly great and ninjas respected him the most and he also defeated madara and taking control of the tails like they were pets,he was truly great that for the title of hokage even some of the uchiha clan picked the 1st and not their leader (madara),even 1 of their own, that should give you an idea how strong he was,still now madara/tobi talks bout the 1st how he respected and admired him the most after losing to him but we knw the madara/tobi has never also said "oh and i also respect the 4th hokage" so maybe in madaras eyes the 4th was noway as strong as the first and that the 4th didnt giv madara a hard time so who will win i do not know but they will never fight each other cause they both from the same village and same hokages, oh and 1 more thing in naruto anime b4 shippuden the 3rd use to always go out in the balcony and look at the 4th hokages face carved in the mountians and smiles idk why but i think maybe he was the true hero of the village, all i got to say and thanx
