The PlayStation 4 may be selling almost twice as well as the Xbox One, according to some leaked numbers from a recent Electronic Arts financial call, but Xbox One users are more valuable to developers. This is according to Ubisoft, which claims that Xbox One users spend $1.25 for every $1.00 that PlayStation 4 users spend, similar to how developers prefer releasing apps on iOS because, despite the fact that Android has significantly more users, iOS users spend more money on average.
