Minimalism is clean, restrained and cool, maximalism is raucous, bold and warm. The minimalist is efficient and precise, while the maximalist is extravagant and flamboyant. Interior designs tend to lean to either of the two extremes and no design theme is ultimately better than the other. It will all depend on the designer and the homeowner. A maximalist person might see minimalist designs as boring, while the minimalist can be overwhelmed by the maximalist designs.
