WHICH NOVEL IS EASIER FOR STUDENTS: AROUND THE WORLD IN 80 DAYS OR THE RAILWAY CHILDREN?

I find 'The Railway Children' the story is simpler and easier to comprehend by my students. I have come across a teacher saying that 'Around The World In 80 Days' is easier. This teacher commented that 'The Railway Children' has too many events for students to remember compared to 'Around The World In 80 Days'. What do you think? I welcome opinions, critiques, comments and suggestions if you find that 'Around The World In 80 Days' or 'The Railway Children' is better for the students.
