The first thing I consider when looking at Express-alternatives is if the API is fully compatible because almost every other 3rd party library/package (e.g. sentry) expects the Express object. This doesn't look like the case as I have no idea what the mojo context object is.

On a side note, I'm surprised to see frameworks trying to use benchmarks against Express as a key feature. Framework overhead is insignificant when requests delays are mostly due to the database/network.
