They are basically the same: overpriced, and neither will work in bad weather.
If you have other options, choose cable or one of the fiberoptic services. We had DirecTV and switched to AT&T UVerse when it became available. 100% better, price, reliability, and service.
Thanks for that excellent tip about ATT UVerse. I checked it out but unfortunately I do not live in a state (AZ)where their service is available.
