I buy the First Lite, Sitka, Kryptek, or Kuiu stuff but not at full price. I buy most on close-out sales, off Camofire, used on forums or Ebay, wherever I can get it at a reasonable price, My camo never matches but critters never care. For colder weather KS predator hunting I like a pair of Cabelas MT050 bibs in the Outfitter camo unless it's really still. If it's really still and I'm trying to be as quiet as possible walking in the wool First Lite Obsidian pants are very very quiet against brush. They are not super durable against thorns, so I don't wear them unless I feel like I need to.
It's spendy but quality, but I have a pair of Sitka Celcius bibs I've been wearing on the ranch during cold weather for 10 years now that are still in great shape. The stuff is tougher than the Carhardt stuff I replaced and far more comfortable. I have Sitka pants that I've abused that are as old. I think the only outer layers from those companies I've worn out are due to zipper failures.
