The Asheville building has some problems, definitely some ugly elements, but I'd hazard that outside the niche world of Chicago/International Style skyscraper fans, most people will prefer the new version.
And while I will fully admit that the shaft of a skyscraper is mostly an aesthetic sculptural element and therefore totally open to subjective aesthetic tastes, I have to say that at the ground level, where the building interacts with the sidewalk and where Jane Jacobs-style human-scale visual diversity is objectively important to good urbanism, is the plain boxy version has serious failings that the new version's more ornamented facade directly improves.
Unfortunately, the new version's improved sidewalk-level facade appears to be totally ruined by a much worse sidewalk & plaza. They're replacing the open sidewalk of the
old version with a curving barrier wall and planters that look like they'll force pedestrians to approach the building from only one angle. That's objectively worse than the old condition, although it has very little to do with the architecture.
