If you're actually doing something better and your results actually stack up under scrutiny I don't see the problem.
I think most people get uncomfortable because it's often untrue in marketing. So if it's true (to the best of your knowledge and after outside probing) then by all means.
Also, I checked the demo and there's like 100kB of WASM code you're not taking into consideration in that React button comparison?
Anyway, congrats on the project. I'm really curious to see how the whole vision will turn out.
