That said, outside is more like the inside of a space suit. You can’t even scratch your nose. But you do have a view, unlike inside which has just has one tiny window. The microgravity would be the most interesting aspect. There’s no way to duplicate it on earth, by the way, which is why there is no way to tell if a new astronaut will get space sick. About 1/3 of them do.
I’ve heard that astronauts who spend months on the Space Station can’t cope with Earth’s gravity once they come home. The zero gravity over time supposedly makes their bones soft and weak, including their spines, and makes their muscles flaccid because there’s no way to do gravity-intensive chores that the earthbound take for granted. I’ve heard that they have to spend months in wheelchairs or on their backs, just to get used to gravity again. Is that true?
