I admit there are many angles to interpret one word. Thus, when people are talking about the same word or concept, it is so common that they are actually meaning different things.
Perfectionism
Perfectionism has a slightly different emphasis on everyday principles to focus on doing things to the best as possible without considering the limitations if time and other resources or putting things back into order. While negentropist admit the fact that perfection is not achievable and fully acknowledge the limited time and resources in the physical world. Some people may think disorder is not in a conflict with perfection, but negentropist only follow the direction that can best reduce entropy.
Minimalism
This minimalism delivers quite similar information with my negentropist believe in the galaxy theory. The ultimate goal is to live a refined life, but minimalism and negentropist are suggesting different daily guiding principles to handle daily choices.
