"his feats seem a little underwhelming when compared to Hashi" - Avery Namikaze
Because people on this website are talking about political leadership when they address the word "feat".
No.
1. First and foremost, Hashirama was revered as the God of Shinobi. And protecting the village from Madara was probably the only good politcal leadership argument he has. He was respected because he was powerful, but that doesn't necessarily make him a good leader, as power isn't everything. (Though it's probably the second largest factor)
Hashirama could have settled his non-violence agreement with the villages in other ways, not boosting their military power like a complete buffoon.
2. Tobirama despised the Uchiha as a whole, whether he accepts that or not matters not, his personal liking to a select few in the clan doesn't justify the fact that he saw the Uchiha clan as a nuisance. The Coup might have never happened if it weren't for Tobirama's rule, and Tobirama also stripped democracy from the election of Hokage, making it an elder selection. And as we've seen from the Manga, the Elder's aren't so wise.
3. Hiruzen is almost as bad as Hashirama, he let Danzo do all his dirty work, he let Orochimaru escape, he let un-allied village into his home village (Chuunin Exams, God that was so damn stupid) He let Danzo have too much word in the Uchiha Coup, pretty much doing his job.
4. The only reason Minato is placed at my #1 spot is because he reigned with no shown negative effects, and died protecting his village.
5. I used to think this way as well, when I didn't look at the big picture. Tsunade's only down side to being Hokage was relying on Naruto to defend the village, that's it. When honestly, Tobirama, Hiruzen, and possibly even Minato couldn't have taken down Pain either. Tsunade made actual peace with Suna, and is loved by her village, and has shown no negative political leadership other than not being able to defeat Pain, which is only something that could be done by 1 other Kage for sure.
I really think you should reevaluate what makes someone a good leader.
