The answer is "it depends". I could cherry-pick examples where Chromium rendering would be circumstantially better, and where Rust's optimization really might make a difference. Ultimately it's up to you to choose the right tool for the job. I've found that Rust is perfectly usable for writing GTK interfaces for simple apps. Those are much smaller, faster and feel better to use than a Chromium embedded app. It's also harder to port, inherently less capable and generally supported by a weaker ecosystem. It entirely depends on the application you need.
