Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Sass

Licensed under the MIT License per sass-lang.com; as open source software it has no paid tier or vendor price to compare
The LibSass and Ruby Sass implementations are marked deprecated on sass-lang.com, leaving Dart Sass as the only actively maintained compiler

Svelte

Licensed under the MIT License per svelte.dev; as open source software it has no paid tier or vendor price to compare
Svelte is a compiler rather than a runtime library by design, per svelte.dev, so components must be compiled ahead of time and cannot be interpreted directly in the browser without a build step
