One thing that I really appreciate about https://omahaproxy.appspot.com/viewer is that it shows me data about all of the platforms side-by-side. I can quickly see whether one platform is ahead of the others, or trailing, or any other such differences.

The Chromium Dash is much prettier, and shows me really detailed data about individual platforms. But, especially if the plan is to ultimately turn down the OmahaProxy dashboard, it would be really nice to have a denser comparison view as well. Unlike all of the other bugs that I filed today, this one is actually pretty critical for my day-to-day work on the metrics team. (Again, the need is currently met by the OmahaProxy dashboard, so this is only a high-priority request if there is some plan to turn down that dashboard.)
