4x4 Alpha/Number Swap

Well can you believe it? This is my third posting today. Wowzer! I finished my 4x4 numbers. I was assigned the number "2". This swap has probably been the longest one I've ever been in. This is the fourth segment and the first was in July. So far I've received 4x4's for the letters A through P, and I'm expecting Q through Z to arrive any day now. Then once this last segment is over I should have the numbers 0 through 9. This round I decided to make each 4x4 different. The past three rounds I made them all the same. Now I have the hard decision of picking one to keep for myself. Hmmmmmm, I can't decide. Which one should I keep?
