I think Michael Miller and Moda are considered to be "better" by many quilters.
The Michael Miler jet black - a wonderful black - shrank over two inches widthwise when I prepped it. (From three different bolts purchased at different times.)
A Moda red print - put out a lot of red and turned the selvage from white to pink.
A Moda intense yellow - put out a LOT of color. Interestingly enough, the dark red, green, and brown from the same line did NOT.
