There are a great deal of Superman/Lois Lane purisrs out there in comics, and I may hazard a guess that the majority of Superman fans prefer Superman to be with Lois Lane. I sense similar sentiment with Aquaman fans and Mera or Swamp Thing fans and Abigail Holland.

However, and I might be wrong about this, but I don't think that there are as many Wonder Woman fans who feel so strongly that Steve Trevor should always be paired with Diana
