Best jeans I ever owned were a pair of 19oz Samurai 710xx. Roughly two years of wear, two crotch blowouts (and two terrible patch repairs done locally), and I think two washings toward the end and this is how they have turned out. They are now retired and sit in my dresser as my greatest denim accomplishment haha. If I could do it all again I would have paid extra to send them to Denim Therapy for the repairs, I did end up using them in the future on my Roy denim and they do fantastic work. The local repairs now feel like you are riding a saddle as they added denim patches to the inside to reinforce the damage.
Second would have to be the Kicking Mule Workshop AWA 1950 circa 2007 from Context. Amazing slubby hand to the denim, it seriously feels like wearing denim snakeskin. With over a year a wear into them they hardly faded at all, have some minor holes in the honeycombs and a soon to be crotch blowout but pretty much zero fading. I had them tapered to mirror the 1980 fit but then sadly outgrew them, I curse the gym sometimes for not being able to wear them. I think I should actually put them up on the market because I feel someone should be enjoying them if I can't. If someone put maybe under $50 into them to hem them up clean and reinforce the crotch they would have a ton of life in them.
I also owned a pair of PBJ jeans that were fantastic, outgrew them along with some Kicking Mule 1980 that I loved.
