While we're talking about what "feels snappier," why hasn't anyone mentioned Safari. It is, by far, the smoothest browser on my computer. It may not do as well as Chrome in the benchmarks, but the scrolling is a thousand times smoother and everything feels quicker.

If the default scrolling isn't to your taste, you might want to try addons like this one for Firefox:

Of course, if you're happy with Safari, by all means stick with it.
