I don’t have particular problem with neck strain (not saying it never happens). I sit 3/4ths of the time while programming/writing. For sitting the angle is nice, standing I’m 100% bending my next to see the RD8, but my work space is an old folding table like you’d get out to seat company for dinner so it is a sitting height to begin with.
I have my Monostation and TD3 on a pair of these guys (picture below) and they are much easier to see and reach while standing. Width wise I’m not sure it would accommodate an AR or Octa.
