I find the Tailwind provides a lot for flexibility in how we approach design for Mojinxo, while still giving me the benefits of a defined framework and centralised configuration. With tailwind we can create something that is very much Mojinxo and not just a carbon copy of every other site using Tailwind, which is what I find tends to be the case with Bootstrap and Bulma.
There is a tradeoff in familairity for users, especially with Bootstrap where users just 'know' how a site will work based on the card display, the common navigation look and feel and the slide-out burger menus.
The icing on the cake is definitely size. Tailwind is just so small, effective and easy to pick up.
