Tailwind is just an easier way to write regular CSS. It doesn't give you prebuilt components. Bootstrap on the other hand gives you a massive collection of pre-built components at your disposal. Bootstrap websites are super-easy to build, but look very generic. Tailwind on the other hand looks unique, but takes some extra thought and design ability to build. Also, Tailwind is lighter because it is essentially a compiler, and strips out all the classes you don't use - unlike Bootstrap. I recommend Tailwind, as it forces you to create a way more interesting site, unless you want something simple and easy to build, then I recommend Bootstrap.
