Martin, I will respectfully disagree with pretty much every single one of your points.
I want to burn charcoal, not charcoal plus binders. Since I've switched to lump, I've found that I really dislike the odor of briquettes, and the brand does not appear to matter. Nor cleaning up the much larger amount of ash produced by briquettes.
You really think you know what goes into briquette feedstock? What charcoal you are getting in briquettes is ground, pulverized, mixed with a binder & molded. The manufacturing process will allow hiding of an awful lot of cheap material. With lump, I can at least tell that I'm getting hardwood (yes, even remnants from other wood manufacturing.)
I won't argue that heat production is variable with lump vs. briquettes. That doesn't matter in my gravity fed smoker with a HeaterMeter, and in my grill with an adjustable charcoal tray, I have very good control over heat at the cooking surface.
