I guess it's a matter of taste but I'm going to have to step in and defend the Billingham bags. They are well made, quick and convenient to use, and look good both pristine and worn. The padding can be rearranged and removed to allow use as a bag for general duties, which I do a lot. Even with a Hadley you can still get a small camera in the front pockets while the rest is full with a laptop and papers, with the larger ones a Leica M plus lens and lightmeter fits in with the rest of my stuff.
In the UK at least, they are not much more expensive than Domke, and A&A is unavailable.
Matches my Barbour as well 😉
