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.
