Love the Octo Finissimo in all of its iterations; were it my cash I would go titanium, as this seems the ultimate expression of the watch's pared-back elegance. That said, I am a clumsy oaf, so brushed stainless looks a good bet for wearing the knocks well and easier refurbing if desired ... then again the ceramic option would repel most scratches...
Hell with what anyone else thinks: buy the watch that speaks to you, and by the sound of your post, that's the brushed version. Hard to see how you could go wrong with any of 'em.
