Chrome is not better because you witness some pages to render better in Chrome. It is actually the opposite: pages are more and more built for and with Chrome in mind. And that omnipresence of Chrome allows Google to force their own moves as de facto standards, which is dangerous overall. Firefox is better because it follows standards and it is open-source and it is not tied to a behemoth like Google. The authors of pages you see perform better in Chrome are indeed not building for the web but rather building for Chrome.
