The Reverse Flash is faster because if you see, in the future when Barry and the Reverse Flash are racing through time, Eobard Thawne was faster than Barry even after Barry uses the tachyon enhancement device according to the timeline. If the timeline stays intact, the Reverse Flash was faster than the flash in the future. Furthermore, since the Flash is faster than Zoom when he received the tachyon enhancement device, no matter if Zoom uses V9, it is concluded that Eobard Thawne is faster than Barry but Barry is faster than Zoom.
