They are totally different shoes, different lasts, the Sanderson is a long wing vs McAllister is a wingtip. One is a blucher, the other is a balmoral. Another big different is the sole, I believe the Sanderson is a double-soled and the Bourbon McAllister is a combination tap sole. Frankly, at $130 I would kop the Sanderson in a heartbeat (which I did ;). Wait for a sale and get the McAllister later.
