Hey

If you want to be polyvalent with minato, just go for hokage.
I buy myself minato jonin but i am full of regrets. Hokage is very strong 1v1 ninja and suit with many teams, but also more usefull for ninja exam, gnw, 2v2 etc If i could go back in the past, i'll buy the Hokage.

The edo minato do not worth his price at moment, imo. Since you need edo hashirama for his bond, it's kinda difficult to use it properly. 3 rounds cooldown kill him. But he still have immunity + dodge + underrated passif which cause tag + ignite
But when edo minato will get his breakthrought, he will outclass the 2 other minato so far.

Jonin is the worst, for sure.

Well, to resume :

- Hokage is the more "balanced", because he suits with MANY teams, very good at 1v1, gnw, 2v2, exam etc. He do not relly on chase to scale, his passiv HURT, his resistance buff is op, his auto deal so much dmg and his mystery deals more than the Jonin's bond

- Jonin is very good when you own initiative + madara 5k. He do not suit with many teams because of his chases. For me he is the worst. His bond do nice damage, but 1 turn / 2.
- Edo is a "noob stomper" atm. Do not even try to get him if you don't own initiative in the majority of your fights. He needs edo hashi for his godlike bond, hard for him to scale since he do not chase from himself. But he can't be control'd, and it's a fcking good thing! He is still very good for space time :3 Less damage than the hokage, less than the jonin'd bond, but he hit throught dodge and interrupt.
