I have never got to grips with DADGAD. I can play in open C and in open G just about as intuitively as I can in standard tuning, but open D, and DADGAD has always eluded me.

However, it is worth noting that Tony McManus, who some would describe as the foremost Celtic player of our time, plays almost exclusively in DADGAD, so it is undoubtedly the tuning of choice for Celtic music.
