Never use forks of popular browsers (exception: when browser libraries are dynamically included from official sources). Forks never get security updates as timely as the originals. This is pretty significant if you are important enough for someone to use their zero-days on.
In general I agree. My only current exception is that I use Brave[1] instead of Chrome on Android, because Chrome is missing adblocking. It appears that the company behind Brave is large enough to keep the fork somewhat up to date (compared with several other forks that are only updated very infrequently).
Also not only security updates are an issue. Some of the previous forks have been maintained by people who hardly had any idea of what they were doing. Interesting blog post about the Iron fork: http://neugierig.org/software/chromium/notes/2009/12/iron.ht...
That's what I did before I knew about Brave. If I don't have a choice I'd use whatever browser provides adblocking, but with a choice I'd prefer a Chromium-based browser.
