Just a personal experience and opinion for CELPIP.
Listening: harder than IELTS. You can not see the questions before you listen the entire recording. Some times if the topic is difficult or you are not familiar with, it is hard to score a 9 or 10 for non native speaker.
Reading: easier than IELTS, each part is about one page long and the topics are normally close to your life. And answers are limited to 4 answers you can choose from. Unless your vocabulary is limited, because certain questions they would ask using different word, it should be easier than IELTS.
Writing: easier than IELTS. Each part is equal weighted and the software offers spelling correction/suggestions. For candidates familiar with keyboard, it is much faster for people to type than write.
Speaking: slightly harder than IELTS. It has more questions than IELTS, and there is no interaction between you and the examiner. And you need to practice to control the time when recording to cover all the required part and finish just before the time is up.
Most importarnt: CELPIP, you need to pray do not sit next to a native English speaker candidate when take the exam. Most of the candidates finish their listening and reading until the last minutes to make sure their answers are correct instead of speed. But some people finish the entire test in 70 minutes, which means when you just start you reading, they are already start typing or about to start their speaking section. It is completely a nightmare if you have such a neighbour like that in your test when you want to concentrate to read. This is what Paragon Testing Enterprise allows to happen and they are not going to do anything about it, just want candidates dealing with it.
