I believe you are correct in that the Argyll is more versatile. The PC, I believe, is recerved for formal and very formal (white tie) affairs. In other words, you don't wear the PC informally. The Argyll can be worn formally,(black tie), but is not considered dressy enought for white tie occasions. Argyll can also be worn semi-formally, as you would a tweed or lovett jacket. I pondered the same question last year....then bought a black Argyll. Unlike my kilts, this was an "off the rack" item.
