Chrome had something of an edge over Firefox for a while with a more responsive UI, but since Firefox Quantum it hasn't really had anything besides some creepy Google integrations.
Edit: Chromium is also easier to embed, but that doesn't really matter for the purposes of chosing a browser.
Honestly, a big change for me was symbolically realized by The logo change: https://en.wikipedia.org/wiki/Google_Chrome#/media/File:Chro...
It went from this space-age, nerdy little project to a cleaned up design that signified its shift to a position as a core Google product.
For me, Google's hold also manifested as complete absence of support for H.264 on Mac, because calling the Cisco's freely available openh264 is ‘too slow.’ In Linux, distro maintainers patch in the support for openh264.
Also, I see no benefit to "trying out Chrome". I use it often for a few broken webpages (blame the devs but there are really few) or on co-workers' computers and find no benefit whatsoever. Firefox has all of its features and much more. As far as I'm concerned: tree style tabs, containers, privacy and flawless ad-blocking.
