Some different brands and perspectives:
(I'm a big fan of super dark indigo jeans or black denim and I like for them to show up so stiff they have to be broken in, so take anything I say here with a grain of salt if you're not a denim nerd)
Bravestar: Around $120-$150 a pair, but long lasting. Three fits: skinny (slim taper), slim (slim straight), and middle-aged dude (true straight). Good black denim with contrasting stitching, which I like very much. They have HEAVY denim: 22oz is like old school Carhartt thickness. Impossible to wear in Georgia for three months of the year. They have a mix of in-stock and pre-order. I've worn all of my Bravestar jeans until the crotch blew out (up to 2 years in some cases)

Gustin: Similar business model to Bravestar, a mix of in-stock and pre-order. A little bit cheaper than Bravestar with comparable quality. Less of the superheavyweight denims. Gustin had some quality issues about ten years ago but the stuff I've gotten in the past few years has been solid. The pre-order takes just long enough for me to forget I ordered jeans, and then one day some new britches show up and I'm stoked.

Dearborn: I have been meaning to try their jeans for a while, but the last pair of each of the previously mentioned brands just wouldn't die. These have a little stretch built in, I think? The next pair of jeans I buy will be Dearborn so I can check them out. Gotta be worth a shot at less than $100.

Levi's: The American standard denim. Almost certainly made by nine-fingered orphans in Sufferistan. Mostly disposable quality but if you need a pair of $40 jeans right now, this is the way. Completely arbitrary sizing because they cut stacks of patterns all at once, so you need to try them on before you buy, even if you know your sizing. The classic 501 fits (and there are like five? I think?) are suddenly hip again, so you don't have to keep cramming your middle-aged body into fitted skinny jeans if you don't want to.
Many many years ago, there was a denim plant in Greensboro, NC (which is basically where I'm from) founded by a man named Moses Cone. Cone supplied denim to Levis until they started off-shoring in the '70s. Cone Denim was the gold (blue?) standard for a century, and when they ceased manufacturing in like 2010(?), some companies bought up everything they had in stock. If you can find Cone Denim jeans, I find that they break in and fade in really cool ways, eventually get butter soft, and breathe well in hot weather. I had some Flint and Tinder Cone Denim jeans that I wore for three years, even getting them repaired with the bike-seat-crotch-split happened. I don't know what the equivalent is, these days, but I prowl the Goodwills and Salvation Army jeans sections looking for anything that says "Cone" or "White Owl plant" on them. It's gotten harder and harder to find Cone stuff, unsurprisingly. It's a heartbreaker.
Anyway, I'm a denim nerd and that's my $.02
