I have the C&J Cordovan Lindrick for RL. C&J makes an extremely well constructed boot and it's definitely in a different league than Alden. Although the shell is dryer, the shaft of the boot is taller, the last is more attractive in my book, and it looks and feels like it's just in a different league.
However the Galway was something that I wanted ever since I first saw it. It seemed like something I wanted to aspire to. The Galway is Iconic. Whether one boot is worth two others you want will ultimately be determined by your needs (needing one or two boots) and your desires to own this vs something else.
Bottom Line: Yes the Galway is more than worth any other two boots that Crockett and Jones makes.
