I want to make it clear right now that this is not about which of the two is better, but rather which of the two has more variety in terms of tools, creatures, themes, settings, etc. I would also like to apologize in advance if this has already been done before.
Right now I'm still not sure which one is more diverse. On the Fantasy front we have stuff like Wizard of Oz, Alice in Wonderland, Lord of the Rings, Narnia, Harry Potter, Game of Thrones, Dungeons & Dragons, and Legend of Zelda. Meanwhile with Science Fiction we have Star Wars, Star Trek, Doctor Who, Mass Effect, The Twilight Zone, Blade Runner, 1984, and Alien. Sure, all of these have plenty of similarities (some more so than others), but all of them, as well as many others that I haven't named, still maintain a certain degree of uniqueness that make them almost instantly recognizable. I'm also aware that both genres have lots and lots of copycats, but I'm hoping that we'll only be focusing on the most popular IPs.
