That is exactly why I have been going on and on about rack dimensions but apparently nobody (other than you avaserfi) is willing to offer a simple opinion on my two choices.
From your pictures it kinda looks like the center channel blocks the lower portion of the screen but it may not be that way in real life. That is one thing that I am trying to avoid and if you cannot place the center in the stand the only choice is to raise the TV so the center can go under it. That leads to yet another problem - the center of the screen being higher than your eye level when seated.
