You should generally be picky about what "Panzer Books" you read. Since a lot of them were written by guys who were motivated by the myths and not by the reality.
First hand accounts are nice, but should be taken carefully. Sometimes guys who were never more than a Private during the war like to think and act like THEY should have been the Generals.
Generally economic and strategic themed books are the best. It's the inglorious facts that are the important ones, ultimately.
Hanz Von Luck's book was very good. Panzer Commander was interesting because Luck was more interested in telling his own story than wanking to any stupid notions or myths.
Guderian's books are good if you want to know how messy and disorganized German military leadership was. It's even better if you want to know why Hitler was the worst manager ever. Written by a guy who had to deal with the most childish dictator in the world every day. Among other things.
