for me it depends on the mood. While I use the HD800 the most, when I wanna listen to rock I go for the Atriums and when I wanna listen to EDM etc I go for the Verite. For gaming the HD800 is king and is just the most comfortable out of the bunch when all I am doing is chat on discord with friends.

I run them all from the same source. When I am gaming I mainly use the headphone output on the RME, when I am "actually listening to music" I swap to the tubes :D
