Love the overall simplicity, prominence of "Vector" over "Branding", incorporation of design element into the font. On #58, using the same color for the graphic element really pops and works well (whereas its a bit lost in #12). I would like to see other colors (but keeping the graphic element one color as in #58), as well as font exploration. #9 is interesting, I like the horizontal justification of the two words. But it has a heavy, serious, almost scrutinizing feel to it - maybe find a way to lighten the font treatment (taller "Vector"?) while maintaining bold color and word mark.
