I would definetly agree that different charcoal has different flavors. I currently have 2 favorites, and am searching for more. I've only ever used lump, so I can't speak to bri.
1)Maple Leaf - Beech, Maple and Yellow Birch. I find this is slightly sweet flavored. Goes really well with chicken and pork ribs, but nice with everything. My favorite.
2)Dragons Breath - I find this is a fairly neutral/clean flavor, and very hot burning.
What I'm trying now is "Hard Coals" and "Wicked Good" both have a blend of south american hardwoods...and I find have a nice flavor for that type of cooking.
I'm trying to find something that is a definate "beef" flavor...mesquite or hickory without being too strong. (If I want stronger flavor, I'll put chunks or chips in.)
Cheers.
