The Nichiren sect's aims are to remove karma and attain buddhahood. Whether they achieve either of these goals remains to be seen. There's nothing wrong with spiritual people becoming materially well off, as long as they don't degenerate into pure materialism. At least they could have more time to pursue spirituality without worrying about paying the bills. Controlling the ego can be a problem.
Tibetan Buddhism came directly from India and retains much of the original Buddhism, moreso than the Buddhism in China and Japan. Tibetan Buddhists fled their country when the Chinese Communists took over and most of them live in India. I've had great experiences with Tibetan Buddhist monks.
Remember that Buddhism came from India and borrows many of the concepts and practices from Vedic religions such as chanting. You seem draw to the Tibetan tradition and that may very well be more suited to you.
