The only chrome variant that doesn’t seem sketchy to install is chromium. The built from open source chromium. And that’s just because some sites barely function unless you’re using chrome’s rendering.
I don’t know that I’d call that a chromium browser but I’ve only looked at its docs for 10 minutes. Hard to say where chromium integration begins and ends there without digging into the code. Seems like, at most, it’s using the web rendering engine from the chromium project. But it also seems to suggest it has its own modules for executing/rendering js/css/html.
Probably not included in the “should be avoided” category.
I'm currently using it in a browser called Falkon. It's not as big as Firefox or Chrome, but it is endorsed by KDE. Also, Apple's Safari is using something similar.
