To start off, I don't really see most of the Spyderco line as being all that good looking. I even think the Spyderco hole looks odd, but it works better than any other deployment method. That's the beauty of Spydercos. They are wicked sharp, and they work so well.
Of those I own, the two best looking are my Carbon Fiber Caly 3.5 and my Sage 1. My SS Harpy has a strange beauty, but my Civilian just looks evil.
Others I like are the Sage 4, Manix Blue, and Carbon Fiber Military. I'd snap up a Carbon Fiber Harpy in an instant.
I don't want anyone to think I'm anti Spyderco, I now own 11, and plan on 3-4 more. It's just that their beauty is in their fit and purpose, rather than form.
