Which bag maker has best build quality?

Like the title says, which bag maker do you think has the best build quality?

I own ULA Dragonfly and AER Pro pack, as much as I love my Dragonfly for its versatility, build quality of the bag is somewhat disappointing.

There are loose threads, and sewing is not even, asymmetry in external water bottle pocket.. etc.

AER Pro pack is heavy, and bit too organized, doesn’t fit much as ULA Dragonfly, but its build quality seems better than ULA, at least to my eyes.
