I really like Tailwind, I see a lot of hate in this thread so I'll try to offer a counter-perspective.
First of all, it's important to understand what Tailwind is good for, and what it's not good for.
Tailwind is NOT a design framework. It doesn't dictate the "theme" of your app. I like to think of tailwind as a tool for writing "clean" css that encourages good UI/UX practices. We need to stop comparing it to Bootstrap.
Tailwind is a tool that makes using "good practice" design simple and easy. If you haven't read Adam Wathan's "Refactoring UI", I'd recommend it. It's a book that helps developers make better UI/UX design decisions, and Tailwind is the framework that Adam developed that encourages a lot of those practices.
On that note, my recommendation is, "Tailwind CSS is AMAZING if you're a small team of developers and you don't have a dedicated designer". Tailwind probably is NOT a great choice if you work with a team of designers and need everything to be super-custom and pixel-perfect.
It's also important to note that tailwind is based on utility-classes. It can easily be used alongside "regular" css. I love that it gives a sane convention for writing that stupid "padding: 4px" class you're going to need. My old apps had crap like this that all did the same thing:
.p-4
.pad
.padding-4
.padding-button-4
After several developers got their hands on the CSS, and didn't realize there were already classes defined for what they needed.
