Your analogy collapses then though because you need people to be able to choose whether to travel at day/night at will for the comparison. Perhaps a better (but still flawed) way would be to say if the Opera browser included a free pass for toll roads and Edge didn't - so with the standard Opera offering you'd be getting a faster journey.

The point to me is that the situation is more nuanced than Microsoft apparently chose to present it.

Well, when you are the person performing the test you can somewhat control the conditions. ;) Opera just chose to drive in the night but sent Edge through rush hour.
