I love the harmony and the way he use musical instrument of the heavy rock he later played (because it's not really metal...).
But still, TOTG is the one of the best album of metal\rock ever to be produce, and my favorite among all of them.
The classical influence on the Nordland are cool too, and the folk\classical guitar song ''Ring of Gold'' is damn great, bringing romantiscm in what could have been ''love'' to the ancient Sacandinavian.
EDIT :
But it's sure that it is not comparable to the older works, for it's impact and creativity, and that it is more ''catchy''.
