CAE vs IELTS Comparison
Both test your main English skills - reading, writing, listening, and speaking. CAE has a 'grammar' part.
An important difference between IELTS and CAE is that IELTS is only valid for 2 years, whereas CAE doesn't have an expiration date.
IELTS takes a total of 2 hours 45 minutes. CAE is about 4 hours long.
In both tests the speaking section is done in front of a live teacher.
You can't 'fail' IELTS - your results are given on a scale from 4.0 to 8.9. You'll only get a CAE certificate if you pass (i.e. get 60%). But both need a lot of preparation and motivation for you to succeed. A pass grade in CAE would be the equivalent of about 7.0 in IELTS.
IELTS isn't easier - just different. Getting into a British university with an IELTS or CAE certificate is going to need the same high level of English.
CAE is less academic than IELTS - the topics are broader, the writing tasks more varied. For that reason you might find CAE less boring.

Best for Academic Reasons
Many universities require a certain score in IELTS to get in. That's why it's taken by 2 million people a year.
CAE is accepted by 6,000 colleges and universities around the world, and seems to be growing in popularity.
IELTS is more academic in tone, which is bad for my students (who are mostly business people) but is perfect for someone who is preparing for University. The writing tasks, for example, prepare you for academic work.
Time Management
You might think there isn't much time management you can do in the listening test, but I disagree. Not everyone prepares for the CAE exam, so Cambridge have to explain what to do in a long, slow introduction. But since YOU know what to do, you can ignore the introduction and get started!
