I have owned every version of KUIU pack ever made, along with several Stone Glaciers, EXO, Kifaru and Mystery Ranch. I will give KUIu some credit in that each version is an improvement over the prior, HOWEVER, they have a ways to go to get to SG, Kifaru level.
KUIU makes a decent priced “production” pack for a guy that goes on a hunt or two a year. I’ve seen a lot of reviews/impressions on here lately with no field use. At least this was not a ”review” post without a day in the field. “First Impression” reports are ok, but need to be taken with a grain of salt.
I won’t take KUIU packs seriously for the mountains until they change their carbon frame. I broke one on a hunt, and have heard of several others that have as well. I want to like them, as their bags are layed out very nice.
Also, your general statement about ”being happy” with any of the top brands is a misnomer as well. Packs are very personal with regards to fit. For example I absolutely cannot wear a SG Krux frame. The XCurve on the other hand feels like it was made for me. Two high end systems where one works for me and one doesn’t. One really needs to attempt to try a high end pack before buying to make sure it fits your body shape.
My intent here is not to “bash” your first impression, as it is what it is. In fact I totally agree with your “first impression” of the KUIU bag in your first post. Your second post is more a victim of circumstance for me as I’m tired of reading reviews of products on here with no actual field use or reviews on products not being used for their intended use. Your last statement put me over the edge...

. “go with the pack with the camo pattern you like the most”??????
