Over the last few years, I've used:
Triple Aught Design
Mammut
Prometheus Design Werx
The PDW design Iliad is my current favorite -

The Mammut is #2. Warning with Mammut, they must use a chimpanzee as a design model. I wear an L in most jackets and shirts, to fit a broad chest and short(ish) arms. Mammut requires a 2XL to fit my chest if I want a layer underneath and it's about 4" too long in the sleeves. Fortunately it has velcro cuffs and I'm normally wearing it in the winter with gloves and other layers, blah-blah-blah. I don't care that it is long basically, plus it was 125 bucks at REI on sale.
Triple Aught Design is a distant third these days for me. Quality has dropped off tremendously compared to TAD Gear (they rebranded as Triple Aught Design around 2010-2011) days but the prices have gone up.
If you notice similarities between TAD and PDW, it's because both companies were founded by the same man, Patrick Ma. Patrick was forced out of TAD around 2013'ish and they kept his original designs (and have done very little in the way of updating them since, just riding his brand). Patrick responded by forming PDW and redeveloping and redesigning some of his older designs as well as generate new designs.
Advantage of PDW and TAD - both
made in the USA.
