Actually David, I don’t think they are comparable. It would be like comparing Hunnicutt’s Sherman book, to some of the Vanguard series’ Sherman books. I’m of the opinion that ‘German Panzers 1914-18’ is aimed at a totally different market, more toward the novice end of the market and as ‘light reading’.
I’ve unfortunately only been able to browse through Hundleby and Strasheim’s book, and as Steven Zaloga expresses in ‘further reading’; “The Hundleby and Strasheim book remains the best and most detailed source in English.”
Maxwell Hundleby and Rainer Strasheim’s “The German A7V Tank and the Captured British Mark IV Tanks of World War I” (Haynes 1990) is presently the definitive English publication on German Tanks during WW1. Pity it’s out of print and where available is comparable in price to RP Hunnicutt’s Sherman book. If you are fortunate to own one, I’m very green with envy.

Landships website is also mention as “Another excellent source of information…”.
