FWIW, I just switched from Windows Phone to iOS -- from the 1020 to iPhone6+. Personally, I preferred Cortana over Siri. And it basically comes down to speed and responsiveness. Cortana is much quicker to launch, and much quicker to find results. I haven't noticed any discernable difference in their query results. And actually, for one of the my most used queries - "What is the weather today?" -- I dont even use it on iOS because the stock weather app is disappointing, I use Yahoo. Cortana telling me the weather was much more usable. Siri is just so freaking slow, that I rarely use her.
