Isn't it whatever the missus thinks is best? I don't have a missus, so I can get away with the sports-heavy PS Vue or YTTV that lack a few basic cable channels that tend to be more popular for women and family audiences.
In terms of reliability, there is nothing better for most users, as has been widely reported by those who have "tried them all," than YouTube TV. Though you may have no problems with DirecTV Now, that's not the experience for a lot of people. However, it's very rare to hear someone reporting of serious, persistent buffering issues or outages with YTTV. And when it does happen, it tends to be an issue with the user's set up (device, app version, home Wi-Fi, etc.). I've only had buffering or disconnection a couple of times, and in those instances, I was having issues with the signal from my ISP.
