I'm giving this a shot for the past couple of days. Have to say I'm really impressed with the whole set of components. They're very inclusive and have a component for almost everything you'll ever need. And the Docs are good. Most of all, it's for Vue 3. There aren't many component libraries for Vue 3 and I'm glad I found this. I've not had a performance issue as of now, everything is seamless.
I am really impressed with its extensive set of components with a variety of modern JS frameworks. Very organised code structure.
