I find broadcasting on the xbox one to be much easier than broadcasting on the ps4. I use an external capture card, and this causes some problems when it comes to party chat on the PS4. For whatever reason, Sony will not let me output party and game audio via both the headset and HDMI. I need this feature so I can hear both in my headset and in the stream.

Microsoft added that feature about a year after the xbox one came out. It's a huge boon to the system!
