This sounds like confirmation bias to me, rather than real world use of both browsers. I use Firefox as my primary at home, and Chrome at work (web developer) and I find very little difference in performance in real world use between browsers.

As for frequent updates, Firefox is a little more noticeable because you see it checking your extensions, but they don't update any more frequently than Chrome. If anything, they still update less frequently.
