HD video? For this? I would think that you should be more focused on quality of the information versus the ability to count the rivets on the aircraft or the eye candy of the user interface.
You'll soon get the retread of the King vs. Sporties vs. Ford Highwing vs. Dodge Low wing vs. Chevrolet whatever vs. Great Taste vs. Less Filling arguments. Plus it's way too easy to overthink this.
For me, King videos, Sheppard Air Written Test Prep, Bob Gardner's Complete Pilot, the FAA books, and a really good CFI-I did the trick.
