Like @cosmicfolklore said, Number One does seem very busy, but, I like how it feels organic and everything feels like it fits and is from the same universe. It's hard to tell with the white background on Number Two being so blown out, but, there's something very clumsy about how the stem meets the metal, just a hard straight line, no flow to the transition. I love the jutting front of Two, but, I'm going to vote for One.
Man, I am torn on this one. 1 is a great looking pipe, especially the bowl, but that stem...ughhh. 2 is a great looking pipe overall and I think I need to give it to 2. If the stem on 1 didn't have a psychedelic split pea soup color, I'd gone 1.
Very tough call, and again I'd be happy with both pipes. I'm going to vote for the more simple, elegant, classic design of number two. The point tapered edge at the front of the bowl is a really nice touch.
