Bootstrap, our popularly known among dev community , is a component-based framework that was designed to help Developers to write less CSS and JavaScript code..
Tailwind is just like bootstrap but not component-based, it's packed with utilities classes .and it's very low-level
I think almost any tool or projects goes with both...reacts , font-awesome, static Website and the like..I can't voice my opinion on this..but as a beginner like me . bootstrap is good , but not the best practices because it's changed the way I write code..I like Tailwind
