C. Hodge's is a fairly standard ST. It's fairly complete, fairly representative of American Reformed orthodoxy of the mid 19th century. CH was in the first wave of travellers to Germany for acquiring his terminal degree, because Germany was where the "cutting edge" was in the early 19th c. CH managed to come back with his faith intact, and maintained a deeply conservative commitment to the Presbyterian Church all his life. His Constitutional History of the Presbyterian Church was a defense of the Old School theology.
It was something of a boast that "nothing new was taught at Princeton Seminary" for the 50 years he served as professor (1822-78). But that is, of course, somewhat misleading. Certainly CH brought back with him from Germany new influences. It was CH's ST that eventually replaced Turretin (in the Latin) as the principal textbook at Princeton (after the Bible, of course). The older ST approach whether north or south (wich see reflected in the southern theologians' lectures, e.g. Dabney, Thornwell) was a bit more organic, a bit more conformable to the Westminsterian constitutional documents. CH introduced something closer to a "global/world standard" approach to ST, following the German penchant for categorizing/organizing and standardizing/making efficient.
The best way to compare CH, and to discover where he said things differently, or offered a different take on some point of doctrine would be to read him yourself and compare to others, of the past and present. I must have 15 different ST compendiums and lectures (if not more) on the shelf, more than I can possibly get to thoroughly, perhaps ever. All I can try to do is read different guys on the same subject, and see how they put things.
Bottom line: Charles Hodge wrote a classic ST, basically faithful to the Standards of the Presbyterian Church that he sought to uphold and defend for his whole life. He was a man of his time--the 19th century. But he was first a humble Believer.
