I'm glad to hear this take. I came from Angular v1 and got sick of the framework churn, so jumped over to Web Components around 2015/2016 instead of going React. I abandoned Polymer pretty quickly around v0.6 because things were changing too much and just went plain vanilla JS + Web Components. I've been building applications since then with just Web Components and couldn't be happier. Unfortunately I just don't have enough experience with React to debate any of these points - I guess I just have to leave it that React is a need I don't have.
