Everyone gets reanimated how they died, with the exception of Madara; Kabuto specifically said he made special mods to Madara to have him back in youth.

So however Kakashi died. With or without the SHaringan, he'd be a force to be reckoned with, what with his versatility and everything. Chakra reserves are basically his biggest weakness, and now it's eliminated.

In fact, despite not being the most powerful at all, I'd wager he'd easily be one of the most difficult to seal. He thinks of plans on the fly incredibly fast. Remember when they were sent to the lava dimension and Sasuk only had time to save himself and Naruto via hawk? Kakashi, in that time, tied a scroll to a kunai, grabbed Sakura threw the kunai into the ceiling, and threw a kunai into Obito's hand to save him.

Now imagine who is this good at weaseling out of impossible situations, and add in unlimited chakra (refills)? He'd be murdering people everywhere. Maybe not as fast as other summons like the Third Raikage. But since his main weakness is nullified, he'd last for longer, I think.
