I do not see why I should downrate the mechanical quality. You may not like the haptics of the outer lens tube, but the lens is no doubt very solid and well constructed.
Regarding the optical quality, I see it below the 24.105 IS in summary. Yes, it has less barrel distortion at the short end, but I consider the large amount of pincushion distortion at the longer focal lengths to be more annoying in the field. And I don't see the Canon far behind in terms of bokeh quality. Both are not really great in this regard.
