It depends on how you like to build projects. If you like the current state of client-side rendering there is no point to using HTMX. If you like server-side rendering (my personal preference) then HTMX fills the gap of doing partial DOM updates without needing to reload the entire page. Some people will argue about perf metrics until they're blue in the face. I mostly rely on personal preferences.
