Right now in my opinion, I'm going for the Studio D'Artisan 103's. I think the fit of these is perfect for me. Not too thin (not ball hugging), not too baggy. Perfect modern cut, not too low, not too high as well. Quality of denim is ok thus far, nothing to write home about (comparing to other standard JP brands) better than american, but not as good as better japanese brands like 45RPM, Pure Blue, or even Oni....but seriously, for my buck, these are the perfect jeans for me, after spending close to a grand in denim in the past 2 months, these are it man. I even considered getting the sulpher wash ones
2nd runner up goes to my trusty pair of non selvedge levi's Premium 527's. I've had these for close to 7 years now, these were the Levis 527 that were sold as the premium line, before you could get them everywhere. The cut of these is pretty different than the actual 527's they made in vast quantities, like slimmer leg, smaller boot fit, and the quality is really good. Although another pair i had did eventually rip in the leg.
in general, I really like the older late 90's Levis premium line/Red line. some real interesting jeans and cuts, and quality was top notch.
