I have had the same experience using Selenium but not with Chrome Dev Tools Protocol. However you still need a stable environment, trustable selectors, and automatic waiting logic to have stable e2e web tests.
I am working on an open source library that generates Playwright tests (uses Chrome Dev Tools protocol) and I hope we can prove you wrong about getting UI tests working reliably. https://github.com/qawolf/qawolf
