Been a while since I switched, but to those who have had DirecTV and Dish, DirecTV has better PQ?

There are way too many variables in the scenario.
No two TVS are identical, set ups can be different, obviously the providers are different.

The Majority of Stores you look at have thiers signal split so many times it's really not a true representation.

If you had 2 identical TVS set up next to one another, and calibrated identical, only then could you come close.
