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. The Flash and Reverse Flash are equal in speed in the future. That was the point of Eobard trying to kill Barry as a child -- neither of them was fast enough to defeat the other. They were exactly equal and opposite to each other. RF also probably had a head start when he went back in time to kill kid Barry, but future Flash was fast enough to stop him, so at the very least, they're equal in the speed; if not, future Barry is a bit faster since he caught up with future RF.

I agree, though, future RF is faster than Zoom, but I'd say Zoom is definitely faster than speed force depleted RF in S1.
