The TV has good support on both; and I think either version will work fine for that.
I would DEFINITELY do version B for the pedestal though.
My reasoning is that, if you look at version A, you are going to have to lean forward to play it.
Your feet can only get so close to it, and the rest is going to be your upper body leaning in.
I personally would make the pedestal lean AWAY from the TV part a bit.
That would give you a much more comfortable playing position.
Alternately, you could slant the kick panel on either version, so that it makes room for your feet to get in farther under the control panel.
