I had no idea at all that there were so many different methods of chess notation. I must have led a sheltered life. (chess wise)
Chess notation

Actually, discussion of a game is (to me) far more enjoyable in descriptive.
I frequently need to correct myself when I hear "bishop to bishop five" come out of my mouth, when I clearly meant "knight five." No matter how familiar I have become with algebraic, having first learned descriptive will hang me up when I'm discussing the b-file. I visualize the correct move, but the mouth gets ahead and takes its own course.

Here's another point to consider. A friend pointed out that algebraic is always noted from the point of view of white. In descriptive, each move is noted from the view of the player who made the move.

From my age and force of habit, I strongly prefer DN to AN, but with this caveat: keeping a game score accurate is a LOT easier with AN vs. DN. The "one-square one-name" method of AN is superior to DN, which flip-flops the back rank according to who has the move. However, if you are inaccurate in writing down your moves, it doesn't matter what form of notation you use, you will be inaccurate. But I love DN--B-QB4 is a move to me, whereas Bc4 is a rather bland statement. BxPch somehow means something to me, Bh7+ doesn't even tell me if violence was committed by this move. I still write my games down in DN, and it's funny to see the younger players look at my game scores and not be able to figure out the opening! Rock on, DN, I'll still use you 'til the day I die.
I use the Short Algebraic or the long Algebraic, I find these two better then the others, simply because I've always used them, and most likely will never change.
ICCF is harder for me because its more difficult to know the move at first glance, I have to think about it more. Also, its nice to know when a piece is taken which is not shown with ICCF.
