Quality difference between brands?

[Invader1]

Seems to be the exact same brands for every shop, L D Carlson, B S G, Brew Craft.

Are they all using the same ingredients suppliers too or is there an actual difference between each's quality?

I would guess there's likely a little difference with light extracts. But there's likely more differences in the darker ones as there's several ways to do it.

I like Briess and use it when I can, though I've now switched to using LME from a California company that isn't a big name.
