The thing that I love about them is how much they seem to hit all the right spots, diverse while always sounding like The Stalin and never like they didn't know what they were going for. They've got fast hardcore songs, weird angular almost post-punkish / no wavish stuff, mid-paced rockers, and sludgey Flipper-esque tracks. I feel like there are bands from that scene who hit a couple of those touchstones, but never pulled off quite as many.
For instance, the Tokyo Rockers bands like Friction and Mirrors seem to tow the line between tough punk rock and more art-damaged, but are definitely not hardcore bands. Then there are hardcore bands who would release a flexi that had maybe two-three straight-forward hardcore songs and a slower Flipper / No Trend-type track. Tam's ADK label roster is really the closest, as far as I've come across, and a lot of that stuff seems to exist in its own shit-fi universe (Kikeiji, Aburadako, Masturbation).
