Switching to Edexcel?

I have been studying in Cambridge for the past few years but might have to switch to Edexcel. Is it a good idea to switch in Year 9? How different are the curriculums? I've been hearing that the biggest difference are the question styles but are the curriculums very different as well? My school has already started CIE IGCSE syllabus so I'm not sure if I can cope with Edexcel curriculum if I switch in a few months.
