Soho gothic is nice, clean and distinct. Maybe a bit too distinct for body, not shure. And I really disagree about Gill Sans not fit for body - it's nice, friendly and readable, after all, typography is about feeling of the characters too, not just the mathematics of what has the EXACT perfect x-height and the PRECISE stem-width etc. Although on the other hand, Gill doesn't belong here, as I wouldn't describe it with "clean and minimal". I think avant garde works well too, although it takes more work to function as body-text (larger type and more space - for good use as body check out Grafik magazine)
