What's the next best thing to WD-40?

Could you elaborate on what you mean by "What's the next best thing to WD-40?" Are you referring to a specific use case for WD-40, such as its ability to lubricate or remove grease and grime? If so, are you looking for a product that can serve a similar purpose but with potentially better performance or characteristics? Alternatively, are you seeking a recommendation for a multi-purpose product that can be used in a variety of situations, similar to how WD-40 is often regarded as a "must-have" item for many households and workshops? Clarifying your specific needs and context would help me provide a more targeted and relevant answer.
