If you look at the early Christian writings of the 2nd century you'll find that Paul's writings, while not ignored, are not given very much attention. In the 4th century Augustine brought them into focus, particularly Romans, with the preeminence of the doctrine of justification by faith. The protestant movement of Luther, Calvin, etc. was basically a revival of Augustinian Catholicism and Romans became the central book of the Bible, the lens by which all the whole of Scripture was understand, and the point by which the Christian faith revolved.
I think on some level Paul though is easier to understand than Jesus which may explain his appeal to the western mind. Paul is quite analytical, particularly in the book of Romans as he is constructing his argument piece by piece, answering objections, etc. Jesus on the other hand can be quite cryptic, teaching in parables and providing signs but never really "spelling it out", it is somewhat abstract.
My preference is not to abandon Paul because I think there is value in what he writes. However, I would rather focus on the teachings of Jesus.
