dont underestimate dealer relationship. If you like 1 company or person vs another, that will go a long way. Better to spend a buck or two more know if you just get a better vibe or feeling from one of the companies vs the other.
Did you ask both companies to speak to references? Do those references have approx the same type of installation as you? If the company gives you a reference of someone who did Control4 in 1 room with a TV/Projector/Lights that is not really going to speak to the type of install you list above.
Lastly, if you do not know what 4:4:4 means, get the JAP hardware if all else is equal. Too many times people chase theoretical #s which cannot really be seen by the human. Sitting in a living room with a TV and windows and ceiling lights and everything - so many variables to get the "perfect" view, I find it hard you'll notice 4:4:2 vs 4:4:4. On top of that, if you get modular hardware, like JAP, you can always swap in new RX/TX devices when released and not have to replace the entire system. I use Video Storm - another Video over IP solution - and the delay or compression is not really noticeable - again something on paper as a number but no person has come to my house and asked about a "delay" or "compressed artifacts".
I had a custom button play the announcement sound in the house of clinking ice cubes in a glass, and the text to speech say "cocktail please"....My wife thought it was funny twice then made me erase it.
