See but that all comes down to personal opinion, and preference. I would never chose a system just because of the controller, or for such a minute detail, that's just insane. The truth is that the sale of the XBONE are lagging, the supply is out there. Almost every store I have called in Miami, they have XBONE in stock, but the PS4 flies off the shelves. Now, every store is different, so I can't say with certainty that is true for all of the US.
This. I made a point the other day to a friend, who stated that loyalist to the XBox will always get the next gen. I disagreed because it's easy to defect with consoles. Unlike phones where all your content is digital and can be transferred to a newer phone, old games aren't playing on newer consoles. I loved my XB360, I was so ecstatic when I got it. I loved playing Mass Effect on it, but simply because the PS4 has identical hardware for $100 less, I would go with the PS4 over the XBONE.
