I recall Kiejok Rinpoche once said to us that the White Wealth God was more suitable for worldly people. And at the time, most student had learned Jimbala ...He then taught us the White Wealth God... My view is that the difference between the two Sidums is at the source of income/ wealth. The Jimbala one is more lottery-alike and the wealth just finds you ( like a gift or offerings etc ) whereas the White Wealth God kinda provide you with a stable job and income.
