I like most genres except for rock/metal. Sometimes I listen to 90's hip hop but mostly on my Radiance. (recording is bad and too revealing on Hifiman's)
HE1000 V2 - any vocal-centric music (pretty much all pop) jazz, blues, classical, orchestral
HE1000 V2 Stealth - EDM, house, some instrumental (especially good with string instruments)
Arya V2 - all genre (really a case of jack of all trades, master of none) and movies
So far I'm finding that one of the biggest downsides of the technical abilities of the Stealth is it's incredibly fast transient response and decay. Along with it's ability to retrieve detail, it makes music sound super technical and revealing but also very lean, and sometimes lifeless. I think it's a trade-off for it's speed, but I feel it loses the richness and fullness of the V2 models. It's especially noticeable with slower paced music like ballads, jazz and classical.
The Arya is the best for movies because it's bass has the most weight to it. And the bass sounds like it's coming from very far out on some scenes, almost like a subwoofer.
Oh and I don't play games.
