I'm looking at compiling a spread sheet to compare React frameworks. (React Semantic UI, Material UI, Ant Design...).
There are some metrics which are un-opinionated tangible metrics (File size, Webpack Tree shaking, No. components) But these don't necessarily communicate the value to the user.
Some things like Material UI (which I'm biased to) have really nice user feedback animations. I'd like to practice better UX and pragmatically evaluate these frameworks for our business use case.
How do I measure these very opinion oriented types of behaviours? Preferably without pushing to production. And communicate these findings to stakeholders?
Perhaps a more basic form of my question is "How to hypothesise the colour blue is better suited to our needs" How do I go about building a case for something design oriented like this.
