Yes, That Ernie!

I use B all the time, but recently installed some phone lines in a doctor's office where he uses a Panasonic non-KSU system using all four pairs, and after the third jack I realized I was using A.

Murphy's law actually came to the rescue this time, because when I went to punch down on the phone module, it turned out that the RJ45 jacks are wired for A. Imagine that!

Then there's the IT guy I spoke with recently who was a bit puzzled when I told him I use B. He was dissatisfied with that answer until I told him that when there's an existing system, I look to see what they used, and use that.

So maybe IT guys like A; phone modules do, too.
A good answer is easier with a clear question giving the make and model of everything.
