I’d say that “Get Buffed” and “Physically Incorrect” would be your best choices. Modern Trends is good if you want to know the best set/rep schemes for maximal strength. But much of the info is found in previous articles of Poliquin’s. I haven’t read “Winning the Arms Race,” but if that is a priority for you, then go for it. Poliquin’s books are not filled with a lot of information for the money. Modern Trends is only 50 pages. It’s a good book, but it really depends on your overall goals. King and Staley’s books are going to cover a lot more information. I like “Get Buffed,” but I acutally think “How to Write Strength Training Programs” is a little better for the advanced trainee.
