As of now definitely jonin minato. Jonin minato scales very well and interrupting EACH round is very very powerful. Hokage minato gets screwed by debuff immunity/tag removal. Also hokage having no chase def hurts.

After skill breaks then I'd say hokage wins in everything but 1v1 as his buff covering everyone and the possibily to mystery the whole bfield basically is just too good. 1v1 tho jonin minato still to beast.
