Everyone has their own preferrence...I buy mine at Joann or Hancocks...actually don't look for who makes it.
My only suggestion to anyone needed black (or any fabric color), buy more than you think you will need...don't skimp! Sometimes our calculations are off, sometimes we make a wrong cut, etc. It is almost impossible to match colors (especially solids) if you run out.
Right now I have 4 different blacks...all 100% cotton, two are Kona...none are the same color black!
