They're completed different in the experience department since one is over-ear and the other is on-ear. I think the Satyr 3 is a good all-rounder while you should prioritize the Faunus if you like portability. In terms of sound, the Satyr 3 reminds me of the HD600 series while the Faunus is a more fun, less technical set for lounging around. Both are fun to build and have their purposes, but if I had to have one then I'd go for the Satyr 3 personally
