Some good React alternatives?

I’ve been plying around with lit-element lately and am finding it a much simpler experience overall. Likely a lot faster as well https://youtu.be/uCHZJy2n8Qs

Lit is excellent.

It's also possible to use htm with Preact for developing without a bundler if your target users support ES6.
