You lose some browser compatibility with qSA, whereas gEBId works everywhere. You need IE8+ for qSA, and you need to ensure the page isn't in quirks mode. If you're OK with that then you can also do: var $ = document.querySelectorAll.

Probably best to do this within a closure so that you're not hijacking any jQuery instances that may be on the page.
