They all resolve decently but I'd say the S12 does the job best However with that you lose out on the bass texture of the other two, also I'd say the mid range tonality and timbre is done best on the nth-100 while that is a little strange sounding on the S12 for example
Stage presentation is generally going to end up going to the headphones if you ask me, the format is generally better at it except for a few exceptions on each side
The S12 is a great IEM i just wouldn't say it competes in the same categories as those two headphones especially due to the two headphones being the best at bass and mids in it's price range respectively in my opinion.
