In general I would say that both exams should not be very technical. They are business oriented, and the way how specific AEM functionalities can be utilize to meet business requirements.
I think that Professional (AD0-E126) exam should be easier, and if this is your first Adobe exam it probably be better to start with it. It is not only about the difficulty of exam itself but also to get familiar with entire exam process.
Keeping in mind that Adobe provides sample tests for both levels, I would suggest to explore them - it will give you good feedback what you can expect also in terms of technical knowledge level that is required, and help decide which one you would like to take.
Thank you again Lukas, that was very helpful. I think I will take the sample tests for both exams and see how I score in each one of them. It will help me to decide the exam I will start with based on the topics.
Yes this is my first Adobe AEM exam. I work as a Business Analyst and I think AD0-E126 might be more fit.
The sample exam is about 15 questions only. I was wondering if you know about any other sources that I can use to expose myself to more questions?
Really appreciate your time and answers
