Which is better,
Cable or Satellite?

This is just a matter of preference. There are pros
and cons to both platforms. Either will provide
television service and have HDTV capabilities.
There really is no answer to this question. Do some research about both services and see what one will provide the best for you.

There is actually a third choice that is not popular or many are not even aware: HDTV service can be FREE via over the air antenna systems. Each area varies what is available but they exist. The closer to a major metropolitan area such as NYC the better (and more available) they become.
