I have more optimism for Ladybird as well. For me, That’s not a knock on Servo and mostly because it was started as a research project, which suggests you’re focusing more on experimentation than producing a product.
I don't see Ladybird ever being seriously useful. Already serious browser projects like Brave, Arc, and Orion struggle to keep me off of Firefox.
Servo is honestly doing the correct thing by focusing on embed-ability into other projects, something that has been basically dominated by Chrome alone
Even just to take screenshots, Servo's renderer is very basic, slow and buggy.
