Unicrown forks don't look too bad as long as the juncture between the steerer tube and the "U" bend on the top of the for is done as clean as possible. Some makers did this with sloppy welds that turned off many bikers.
I suspect that the Unicrown was invented more as a cost saving design to eliminate any sort of crown on the fork. I'd still always prefer a "crowned" fork even if it is full sloping and flush. The rounded, "weak" bent shoulder looks of the unicrowns just does not get me excited about their looks.
