First one I read of was Ted Knight in an old Wonder Woman, back when her book was about adventures in Earth's 2 WWII, and I liked him immediately. First one I followed with a certain regularity was Ditko's Prince Gavyn over at Adventure Comics. But my favorite was the late 80's Roger Stern and Tom Lyle's Will Payton. I miss him so much. I liked Robinson's Jack Knight, however, IMHO, he, and none of the others, can't hold a candle to Will Payton.
Peace
