OTR and Tristessa?
Tristessa is interesting, but thank god it was not the third best thing Kerouac wrote. Subterraneans is also very good (one of most people's top 5), but I havent read it in a while.
Dharma Bums does veer into "an ill-considered orientalism", but I dont think that means its closer to Pic (Pic is one work of Kerouac's that I consider "highly problematic").
From your response I can tell you enjoyed the end of OTR more than the rest of the book.
