As most wides are retrofocus, not sure what you can use. However the look of the 14-24 for me is very nice. Can't see the HDR comparison, as HDR has nothing to do with wide focal focus, at least to me.
As previous mentioned I guess you will need to step back a bit or go to the fisheye style lens, of which the look is a lot more stereotypical to me than the retrofocus look from the 14-24 or any other wide.
You might also look at the 17-35, as it's optical very good and not quite as wide, may see less of the aspects of retrofocus element, (widening and flattening of objects to the edge of the frame). Plus it takes normal filters and does not have the outer curved element which is flare prone.
