How to approximate an arbitrary fuzzy subset by an adequate extensional one is a key question within the theory of Extensional Fuzzy Subsets. In a recent paper by the authors  different methods were provided to find good approximations. In this work these methods are compared in order to understand better the performance and improvement they give.
