I would just say that the sports offering looks very similar to what PlaystationVue offers in their Core package at $45/mo. A bunch of channels come under the ESPN banner, ESPN, ESPN2, ESPNNews,ESPNU,Big10Network, SECnetwork. And a bunch come under Fox, FS1, FS2, FSPlus. And then you have NBC, with NBCSN, and the Olympic Channel. And, then some standalone like NBAtv, but I don't see NFL channel, which PSVue has.
For me, the big difference is PSVue has 5 simultaneous streams, while YTTV only allows 3. If you watch 2 games at once, or have a family, being able to watch more than 3 streams simultaneously is crucial. Only PSVue, as far as I know allows that.
The DVR feature is longer for YTTV, 9 months instead of 1 month. That's very useful on PSVue, compared to SlingTV or DirectTV, etc.
But most importantly, I'd rather not give Google more info about me or my family. PSVue works great.
