Sure, I was more speaking to usage... I'd have to imagine that querySelector* dwarfs evaluate in actual usage. Chrome's stats put evaluate at about 5% of loads; I'm not sure they have tracking for querySelector.
Of course XPath has its place and is the better tool for some situations. On the PHP side XPath has been supported for a long time, while the querySelector stuff is quite new.
