I agree with this assessment. One of the issues I had with the GoF patterns book (from the perspective of one's first book on patterns), is that it's heavy reading for the target audience (i.e. people clearly not exposed to patterns before). If you're in that situation, you'll struggle to stick with the book and appreciate it. For everyone else, it's probably preaching to the choir.
This book on the other hand - while perhaps lacking on implementation details - does a wonderful job of introducing a variety of patterns and their usefulness as abstractions.
