That stuck out for me as well, I could argue that Chrome isn't a better browser than Safari for me, but functionally they're both using WebKit so they render sites identically in most cases.
Sure, there's a lot going on that makes Chrome a great browser, but it's still not my daily driver as I prefer Safari for a myriad of non-technical reasons. I like the iCloud tab sync, the Twitter integration, the fact it looks significantly nicer than Chrome in terms of blending with the system style (which is arguable given how little else tries these days from Apple's own applications).
