To be honest, When i started playing darius i was following your build, it worked well, but as u know u just cant play 50 games straight with the same champion, so i decided to play with ezreal a few games, with ezreal i build my sheen really early, and after a long time of not using sheen i noticed how good it is, and how high the burst damage is if you use it right, so after a few games i decided that ill try out darius but with a different build, this time using a sheen.
Worked even better then your build for me, so i decided i'd try to make my own build, and there it is, I sayed it is unique because it is, most people build theyre darius just like you do, but never came across a single player who builds it like mine.
Besides, If you didnt notice my guide has a link to your guide too, for players who want anything more then just the ultimate tips.

It isn't very unique at all, looks exactly like my build with a trinity force instead of frozen mallet. XD

Nice guide! Works well.
