Alright fine, I'll bite. Zoom stealing Barry's speed might not have made him faster. What is confirmed though is he's been using Velocity to repeatedly bolster his speed so he's far beyond a standard speedster.

Pre-tachyon Barry was never able to catch up to Zoom. After he leaves the Speed Force he easily caught Zoom (even without tachyon). So either Barry got faster or Zoom got slower. Simple.

If you want to be really meticulous, yes it's not proven that Zoom is faster than Eobard. But it's not because of the reasons that Eobard "looks like he's running faster", because Barry was slower back then.
