Yes, there are science fiction authors who do good characters. Lots of them, even.
However, I would ask you to consider how many of those stories take place in a literally different shape of space-time.
Not just lip service to vaguely handwaved "strange space-times" in the style of Lovecraft, either, but extensively realized alternate geometries that drive the story.
There's a reason you don't get all of these things at once. At least, I can't think of a story that hits all these points at once.
Btw, I'm not expecting you to change your mind about Egan's work. Even by the standards of science fiction, I'd consider him a niche taste. If he's not to yours, party on and enjoy what you want to. I'm just trying to explain his work.
