The Super Sports Pack is garbage. Everything is in standard definition and it looks like a 1982 VHS tape on a high def tv. Also the guide doesn't work properly, games missed for whatever reason and just plain bad service. In all honesty the quality is very close to the feeds you get from the sites on the internet that upload the streams.
It's a choice that really comes down to economics. It's costing me more than double with Bell and that doesn't include NBA, OHL, and Nascar (which I'd never watch) that also comes with SSP. So I guess if Bell were to offer those it would be over triple the price. But getting over 80% of the content in HD is huge for me and is the ultimate difference maker.
That being said, I contacted the NFL to find out why the difference between cable and satellite and have yet to receive a response. I submitted my question through their website because I couldn't find a phone number anywhere.
