Yeah, I don't love the physical Apex 2016 head unit design either. I cant tell if it was intended to look modern or not. Somewhat weird looking, just like their DOS & Trident. Provocative design? Kind of sets them apart, in either a good or bad way depending on your preference.
I think Neptune's main design decision for the head unit is based on the assumption that the majority of users want to mount the system to a panel, so cables should exit downward. Then, instead of having a wide unit like their older Apex Classic, they made it thicker to minimize the space needed on said panel. But then the ports are laid out so weirdly, how will users ever plug something in??? Add the rotating component ;Woot.
The GHL controller cannot really be be wall mounted in most setups since it protrudes so much, and the cord exits the back. Designed for a shelf. Which concept is better, wall mountable or designed to sit on a shelf? Impossible to determine!
I do wish I had the funds to just order a GHL controller and get familiar with the features and hardware. I could design several accessories for their system if I had one in my hands. It might be a good investment!
& Thanks
edit:
Also, on a side note, the upcoming Control2/Control4 from Coralvue is designed to be wall mounted, but with the IP67-rated ports facing outward. Just like their WaveEngine. Its an interesting look (plus lots of RBG!).
