Why Chrome?

[Moltke]

Personally, concerning Linux Lite (Ubuntu based), I doubt there is a single real reason why Chrome or Chromium is better choice.

Actually, Firefox is slow and very resource hungry.

Answer with a technical real reason why Chrome/Chromium is a better choice. Good luck, because it definitely is NOT a better choice

I'm not sure what you're asking to be a "technical real reason" since you started by giving your personal opinion on why you think Firefox is a better choice.  I don't really like chrome, but chromium has proven to be a very reliable browser, at least that's been my experience so far. In any case, web browsers are a matter of tastes and needs, whichever works better for you then stick to it till it doesn't anymore and restart the "best web browser" hunt again lol...
