Best revision guide for Economics edexcel?

So I have the CGP, it seems very I'm depth and good, but also there's another student guide split into 4 books for each theme. I don't know which to base my revision off, there's good reviews for both. But me, being a pessimist only wanted to see the bad reviews for each. CGP being big has a lot of good reviews, it's not got one bad review below 4* to do with content but rather delivery speed. There were 4* reviews by professional reviewers one saying it's not enough also for your whole revision in "isolation", and was similar for the other book, but the other one had a bad review saying it's a little generalised, only good for getting a C, not an A or A*. Whereas CGP, I felt was more crammed with useful info.

So both reviews had one review saying a little too generalised etc. But CGP had 75+ good reviews where as other book had 4 separate books, and the boom with most reviews had 19, not all being 5*. So please give me opinions, I'm generally indecisive when it comes to my own situations.

I do plan to use other forms of revision like videos.

Below is the non CGP guide.
