Transformation of skewed independent variables with negative values

I have a bunch of independent variables which are skewed and have negative and zero values. I am seeing a lot of suggestions of using cube root as a transformation. I want to ask what is

What would be the harm in using this$\text{sign}(x)\log(1+|x|)$ instead: Sign(x)*log(1+Abs(x))?
