I use Vuejs for most of my projects and I love it. I have worked on Angular before and I in fact learned Angular first and then moved to Vue. I personally felt Vue was very lightweight and far comfortable than Angular. I didn't get a chance to code anything on React yet but hopefully, it can happen soon.
Web components is definitely a great breakthrough and I was actually expecting this to come sooner or later. Web technology is progressing really fast. I'm glad and happy to use Vue for my projects. Cheers!
