Meyers vs Lammle?

Steamrolled

Hi, I'm new to these forums and I'm glad I stumbled upon them. I just got off a course from a local occupational center using Online Expert and Cisco's Labs/Packet Tracer. I'm looking for something I could read through, take notes and feel ready to take the test by the end of the year. I enjoy digital content such as a portable PDF and practice tests but its not necessary since I'm not travelling all that often currently and I still have access to the 'Master Exams' from the Online Expert.

Here are the ISBNs

Meyers 6th Edition amzn.com/0071848223
ISBN-13: 978-0071848220
ISBN-10: 0071848223

Lammle 3rd Edition amzn.com/1119021243
ISBN-13: 978-1119021247
ISBN-10: 1119021243

Thanks in advance for your replies, I'll be checking back soon!
