Icon for Navigation is Web

We've got a couple nav icons out there, the three lines and the arrow. I prefer the three lines but I've also seen that it's not a common character. I've even use a two line icon (the equals sign) so it wouldn't need to be an image. An icon font is a good way to get around this, but is the three stripe the best icon for a menu? It's also used in browser apps for the settings button, so then you get the same icon in the same space, although if they serve the same function then perhaps (although it looks odd) this could be seen as a good thing, no? What do you think?
