I take Economics and Geography edexcel~
CIE is more harder and you need to learn lots of additional topics so basically it's broader and you can find more exam papers on the internet avaliable for the students
yet for Edexcel, the syllabus is more helpful for example, it tells you exactly what you need to know, you need to know less topics unlike with CIE, maybe just like two topics less. It's hard to get Edexcel past exam papers, and i don't like the way they put up the questions, more of what you can 'memorise' i would say or questions that are out of the topic and depends on comprehension.
Edexcel is easier generally, but it's not better! and this year's geography paper was one of the worst papers
