I've been using GA's visitor flow for a few months and I still think its presentation is really neat. It only shows the first 3 pages viewed, at least on my free account.
I suspect many people still don't know about it, since it wasn't featured upfront like Mixpanel is featuring Flow here. One of those low-profile upgrades that is really quite useful but left unmarketed.
edit:
Another thing is that GA's flow presents the actual size of flows visually, whereas Mixpanel's doesn't - the sizes of the circles are based on step number, and you have to mouseover the small points to see the traffic flow percentages. I have to say Google's is superior, at this point.
