Ladybird is developing at an impressive pace, but it's nowhere close to being as usable as Servo, and it'll probably take a while before it can be. Even with the experienced and skilled developers Ladybird has attracted, it'll take a few years before it can compete with a project that had whole teams working on it full-time.

On the other hand, it could well become the de-facto standard browser for embedded applications, though. The browser frame can be ported to different UI frameworks quite easily and the code has practically no dependencies outside the project itself.
