It definitely does. Chrome is borderline unusable on 8GB RAM - more than a few tabs open make it go into swap hell, while Firefox works well with thousands (Chrome doesn't even have the concept of unloading open tabs!). Also, you can't even disable tab shrinking in Chrome, let alone move tabs to the left border of the window, as I do with Firefox. This results in an UI that's practically unusable with the only way to navigate the tabs being the mouse wheel.

Chromium used to perform visibly better than Firefox with somewhere around one to five tabs open, so sometimes, if I didn't have the browser running and didn't want its full session to load, I've started Chromium just to quickly check one URL - however, recent versions of Firefox made it comparable in such cases, so the only use case for Chromium I have now is to deal with badly coded websites that assume it's the only browser out there.
