False dichotomy. Your only options aren't HTMX or React/Vue/Svelte when web standards like custom elements have been here for years, are smaller, faster, and work with all your browsers (including the ones on your phone).
Love Lit. I've pushed hard for Web Components at work for a while now with some success (the shine is definitely coming off of Angular for a lot of people there) and I've only used Lit to build my personal projects for a long time.
I love it when I visit one of my pages and use Lighthouse to check it out and have nearly straight across 100 scores. Also, I usually have really great performance on phones as well because the pages are so light and quick to render.
