With a quick glance it looks like Blunt has fewer classes. It seems to be more of a utility + whatever-css-method you choose, e.g.BEM. Blunt has utilities for margin, padding, height, width, font size, line height, grid and classes for row, column and some text alignment utilities. Tailwind includes border, font color, transitions, background color, etc. I'm using Tailwind on a project right now. My first one. I like it. But the big appeal to me is using the same classes on all of my projects. It's less cognitive overhead than coming up with names, dealing with scope creep on classes, etc. That said, a buddy of mine that is a much better web developer than I uses Sass to make base utility classes and a BEM like approach for the rest.
