Heh, I never put together one of these lists, so I figured I would, just for fun. Disclaimer, I own all of these jeans and my list is ranked in order of my preference and wearing frequency.
1a) 5EP Low Down Boot Rigid
This is a great pair of jeans, wonderful details, including hidden rivets and chain stitching, and it's very understated and the denim is just wonderful. Fit is great too, and it doesn't really even look like a bootcut.
1b) Ande Whall Cougar
This jean is very dark, extremely well made, and an awesome fit. I like the Cougar fit slightly better but the 5EP has wonderful details so I'm giving these a tie.
3) Nudie Straight Sven Dry Selvage
While this jean isn't quite as dark as the other two, it does fit quite well, with a nice low rise and reasonably slim fit. I did have to have my pair tailored from the knee to the ankle but with that modification it's one of my favorite pairs of jeans. I'm ranking it below the two above it because I prefer very dark denim and because I had to have it altered.
4) RRL Slim Fit Selvage
The RRLs are great jeans with extremely nice details, a nice slim fit, very low rise (too low for some, probably, like 9-9.5" for 34") wonderful dark denim, and best of all, very low pricing.
5) Studio D' Artisan SDA-103
One issue I have with many repros is their relatively high rise. The SDA-103, however, has a nice modern cut with low rise, dark, smooth denim, and slim fit. Having muscular thighs and calves, some repros are hard for me to wear, but the SDA-103 work very well.
6) Nudie Regular Ralf Dry Selvage
For a long time the gold standard here, I think the RRDS is actually an underrated jean. It is a cut that looks flattering on most, with a not particularly overstated bootcut, and nice Japanese denim. What's not to like?
Rag & Bone makes a wonderful pair of jeans with extremely dark, nearly black selvage denim, wonderful detailing and quality of construction, and a great fit.
8)APC New Standard
This jean is relatively inexpensive, with nice denim that is durable and fades well. It also comes with quite a long inseam which is attractive to some people. Not quite as attractive is the strange and sometimes variable sizing and relatively high rise, but it's still a nice jean.
9) Sugar Cane Okinawa 40301N
While I didn't get the more expensive natural indigo variant, I still like this pair of jeans. They are quite relaxed and I would recommend sizing down at least one size, especially if you aren't going to wash them. The feel of the sugar cane fibers gets a little bit of getting used to, but the feel is unique.
10) Julian Red California No Wash
Another Swedish jean, this one is quite slim fit and has nice dark denim and a low rise. A nice modern cut and nice detailing probably make up for slightly lower quality of construction than some other jeans on this list. I'm quite fond of my pair.
