I have not used these specific books, but my previous experience with Packt has been hit and miss with majority being more towards the miss. Some bad practices I had to unlearn, poor writing and overall not a super enjoyable experience to work through. I usually jump on the O'Reilly published books as well as the Manning books. If it is a Packt bundle, I usually just try and find the same topic on a free youtube video or I just read the documentation directly.
