Ladybird is further ahead than Servo, at least with what it can render and how correct it is. But Ladybird is a lot slower at this point.

One reason of course is that Ladybird wrote its own JavaScript engine while Servo uses SpiderMonkey.

Ladybird scores over 500 on https://html5test.co which is better than Firefox 60. And Ladybird is not too far behind Safari on the Web Playform Tests (ahead of Servo).

I wish both projects well.
