He has the ability to take down the Six Paths of Pain without knowing their abilities, and only in an imperfected Sage Mode (if he didn't leave the 3 Pains he killed just randomly on the floor, but sealed it or something, he could've possibly killed them all). If he happens to acheive a perfected Sage Mode, I think he would possibly be stronger than Naruto, or even Kabuto if he didn't have Sage Transformation and all those DNA hacks.

For a character that doesn't know Sage Mode, I would choose Tobirama. He knows about Sage Mode, so he would know the abilities of it too I would assume, and with his experience and skills, he could've easily created unique or extremely OP senjutsu. But there's a chance he's also the speedy type with the use of Flying Thunder God and stuff (like Minato), so I'm not sure if he would like the idea of staying still in battle (to gather Natural Energy).
