Interesting remark. Some weeks ago, I mentioned something about a potential SW mix and said "...if he really gets it right", and someone made fun of it as if I had said something sacrilegious.
Actually I'm a big fan of him, both as a musician and as a mixing engineer, but I don't consider everything he does to be flawless either. Most of the times I love his mixing decisions, but occasionally it doesn't work for me.
I'm also a fan of him (musician and mixing). I generally like his surround cohesive mixing decisions, but...
I don't like the old SW mixes (5.1 and Atmos) when he used mainly the Center Channel for main vocals. It gets too isolated compared with the more broader stereo on both FL,FR channels.
I also don't like previous SW Atmos mixes that are limited to 7.1.4 channels. Even using some Objects, the Wides locations were barely used.
More recently, maybe at the same time Bruce Soord has evolved from mixing Atmos with the vocals only on sides (difficult to get a stable binaural into the head sound) to the extensive use of Wides together with Front Heights or other channels to give a more "Wide-spherical" surround vocals. Steven Wilson has adopted also a similar technique and I listen more and more SW mixes that use the Wides with Vocals or other sounds, and the vocals are not more Isolated in the Center.
I like how Steven Wilson Atmos mixing is evolving, in line (more or less) with the Bruce Soord mixing evolution.
