He's smart enough to build it, but I doubt smart enough to build it by scratch like both Harrison's did. Thawne figured out the speed equation, something which both Earth 2 Harrison Wells and Barry could not do. Sure, E2 Wells created a device to steal Barry's speed, but that doesn't mean Thawne couldnt' do it. Thawne simply did the bare minimum to get what he wanted, "nothing more, nothing less". He planned it for years, so he must have thought of the most efficient way to achieve his goal.

Anyways, this is just speculation. What we do know is that Thawne solved the speed equation, but E2 Wells and Barry couldn't. Thawne Wells used to help Cisco on everything, not just things related to speed, so clearly he must be smart in general, not just average but obsessed with one thing. I think someone already mentioned that people would easily notice a very intelligent person become average or stupid, especially since Thawne Wells existed for years upon years. Oh, and given that Thawne Wells can speed read like Barry, he could store and process information far faster than Wells on a technical standpoint. Heck, some people think this is how Zoom was able to become an experienced and talented scientist so fast after he broke out of the mental institution.

So yeah, I'd go with Eobard Thawne Wells.
