Fair enough on the experience and extrapolation. But I would argue your analogy is a bit off. It's undeniable that a lawnmower is faster than scissors. I don't think that's the case between React and no React.

A closer analogy would be a comparison between different models of lawnmower or between a lawnmower and a different kind of mechanical grass cutting device. In which case, it seems you would need to log time to see if you've saved time using one over the other.
