I'll be blunt, I'll always take Superman over Captain America, even though for the most part, I'm lean more towards Marvel than I would DC, but the fact is, Superman is to me, the more iconic of the two, and that's why I made this thread. What would happen if, not only do these two trade places, but along with them, their actual influence, renown, and fame that they carry in their respective universes carried over with them? How well would they influence the new homes? How would you personally like the change in this happened for real and both companies traded characters? What kind of relationships can you see them forming with a number of character in each universe?
For example: How Do you think Superman would feel about Spiderman, Hulk, Thor, and Tony Stark? And just the same way how would Captain America feel about Batman, Wonder woman, Captain Marvel, and Flash?
