At work, we use B standard. It doesn't matter what you use, but whatever you use - make it the standard.
It's nice knowing whatever cat5e end I put on an ethernet cable that I know what pattern I am to be using right off the bat. If you use A standard here, B standard there, etc, things will eventually cross over, and you'll find yourself in that situation where you have 1 shot to put an end on right and you realized you just made an A/B cable and have no more ends. Now that's a recipe for a good day!
