Servo is very promising, but not ready for commercial embedded applications yet (as of approx 3-4 months ago last time I checked it).
It will likely be a better engine than embedded Chromium when it's done (if for no other reason than that it seems to have fewer dependencies[0]), but I wouldn't start building an application on top of it today.
I am highly interested in finding a more performant alternative to Electron. I'm currently building a web-first game that will also be available as a fully offline native app. I'll probably use Electron unless the ecosystem changes drastically before I'm done. Some really interesting projects out there -- not just Servo, but also thin wrappers around OS web views, even a few re-implementations of CSS/HTML that just force you to cross-compile or port your Javascript to another language.
But I haven't found any that were mature enough that I felt comfortable using them. Servo was the most promising project I personally have seen so far, but it needs more time.
