@DK12, please don't take this the wrong way. I don't mean to come across as a jerk, so please forgive me if this response comes across as such. And sorry if I get wordy as I tend to be:
The paper and pencil is no longer offered vs the CBT as far as the Electrical "Power" exam goes, so I really don't see the point in comparing the two exams.
I've been told evidence suggests (or in fact, shows) that the overall passing rate has crept higher for most disciplines across the board which have transferred from paper/pencil to the CBT. This may imply that for the most part, overall the CBT is slightly easier than the paper/pencil exam.
As for my personal experience (I took the paper/pencil in October 2018 and October 2019, and the CBT in December), I felt the
overall difficulty of the questions and the wording of the questions
was about the same (paper/pencil vs CBT). What helps is not having to spend as much time opening a book and flipping to a page to find what you're looking for, versus using the search function on the computer and knowing you have limited resources to look through.
I found the overall process of taking the CBT a bit easier than the paper/pencil. The time starts when YOU start the exam (not the proctor) and the search functions allowed me to finish the exam faster, so I could spend more time on problems I wasn't sure of.
Here's an example: On paper/pencil exam you get a qualitative (theory/conceptual) type problem. You know you have 2-4 reference books which could point you toward the answer, and even if you've tabbed the right section, you could either get lucky and find it in the first book you open (30 seconds), find it after opening 2-3 books (a couple mins), or go through 4+ books and never find the answer and have to guess or narrow it down to 2 choices (5+ minutes). This won't happen on the CBT. If it's not in that particular section of the NCEES reference guide when you search for it, you either know it or you don't, and you have to rely on your memory or your understanding of the concepts. Therefore, there is a balance between being able to quickly search (a little easier because of the CBT format), and having to rely on memory/concepts on what you've learned (harder because of the CBT).
Overall the amount of theory/conceptual problems was about the same. The topics and percentages of each subject was about the same.
I hope I answered your question(s)!
