Having flown the P-38 personally himself as-well as shot numerous of them down I must admit I'm inclined to believe him. Esp. when coupled with the general opinion of Luftwaffe. Galland btw even goes as far as to say that the P-38 was a mistake to manufacture.
There is also a comparison it Dietmar Hermann's book on the 190 IIRC, where the P-38 is compared to the Fw-190 by summerizing the opinion of pilots from some of the Jagd Staffels, and in that comparison the P-38 was indeed mentioned as an easy foe.
