Joe,
If they work for you they are not wrong and I doubt you are missing anything, that part is pretty simple.
There are several factors involved in my rejection of A-2 steel for chisels. The biggest is needing special sharpening media and slow to sharpen and next is weakness of the edge at more acute bevels. Sometimes for paring I like bevels of less than 25 degrees, A-2 edges tend to be weaker below 30 degrees than high carbon edges.
I'm in the sharpen as you work school. My sharpening bench is a couple of steps to the left of the main bench and I freehand sharpen so edge retention is lower on my wish list than ease of sharpening and I dislike the mess and fiddliness of water stones. At one time LN offered O-1 and A-2 steel in both their chisels and plane irons, I think they made a mistake when they dropped O-1. Of course as with all things wood YMMV.
