I wouldn't say junhashimoto dominates Attachment hard in the quality department. Both are very nice leathers. However the one Attachment leather I own is not better quality than this particular junhashimoto one. Also realize that most of junhashimoto's leathers are priced at one of two levels: 147,000 or 173,000 yen. Mine is the higher priced one, so perhaps it's better than the others you may have seen. If you like badass CCP type stuff, then I'd imagine you'd fancy Attachment leathers more than jun. Many of the Attachment leathers are remarkarly similar in style to CCP. Personally I feel like I'm increasingly moving away from the whole dark lord / mad max look that these labels embody. So that's probably why I seem biased towards the jun stuff.
