Best brand of coco?

I've spent a lot of time on google, and yielded very little results on the subject. It's hard to tell one coco from another in terms of quality. I see a lot of coco loco at my local hydro shop, but after reading all the ingredients it looked more like soil than coco? I think I would prefer something bagged rather than a brick. But im pretty unfamiliar with the medium all together. I use sunshine advanced at the moment. What do RUIers use?

I'm using Bio Bizz's Coco Bizz. I like it. These no permits or anything else in IT though, so keep that in mind.

I've used both Canna Coco and Mother Earth with no problems.
