You don't need data to know that the initial product will be the least optimized (in terms of speed/power) and fewest apps. I was speaking mostly in the domain of Ubuntu phones, since the experience will likely improve as they develop the product more, however I would be very surprised if Canonical manages to be faster and more efficient than either iOS or high end android devices at launch. I'm not saying they there isn't potential, I just don't have as much faith in Canonical as you seem to.
