Rear entertainment system or no?

So we finally settled on an XLE after driving one and thinking that we do need the front parking sensors that the LE doesn’t have since the vehicle is so big. However we’re torn between getting the rear entertainment system or not. We have found a few coming in that have them but haven’t found enough reviews of whether it’s worth it (quality of display and ease of use.) I know that we would have to use an HDMI cable with adapter if using iPhone. Anyone have any thoughts?
