I didn't really feel like bitly and referly were head to head competitors, but the new "public profile" pinterest type functionality makes it feel more that way.
The only thing referly is lacking are really detailed analytics (the "Bitly Pro" stuff). I suspect they'll add that over the summer.
We've got some stats visualization built in already and getting to it is a bit subtle - you hover over the table cells in your list of links on the account dashboard, then click on "more info" - but agreed that yeah, we could do a lot more there.
