As I remember it one of them is for stranded core wire and one is for solid core wire. Both A/B do keep the RX and TX pairs matched which is the electrically important thing. Using the right standard for your wire is only important for that last aspect, what happens if someone else repairs one end of one of your cables after it is buried under the floor. If I use B when I should have used A, I leave it be, but I fix or trash a straight through cable whenever I see one, depending on it's condition and location.
