1848 or 1968?

Seeing all the uprising, the general crises, etc., which revolutionary year do you feel it is more like? Feel free to suggest other "sweeping change" years if you want. I left 1776 and 1789 off the list as they seemed too narrow, but am open to argument. Understandably, both of my choices are fairly Euro-centric, so if you've got something that's a better fit outside my blinders, I'm also interested in hearing that.
