I'd say Reverse Flash as he was a match to OT Barry, who didn't have the same issues holding him back as CT Barry. It was implied that the reason Barry wasn't able to increase his speed was because he couldn't move on from his past and was unable to increase his speed naturally as a result.

If that is so then OT Flash would continue increasing his speed without limit from the day he got his powers, so if RF was his equal and opposite he would have to be a match.

Zoom meanwhile was stuck and Mach 8-ish for a long time and then whatever speed he had when absorbing Barry's Mach 2 level Speed Force connection to cure his Velocity sickness.
