It's not a decision like which ice cream flavor should I choose today

Should I choose an ordained certified Nichiren Shu priest, Nichiren Shoshu High Priest, SGI "eternal mentor", or some other intermediary, or  should I choose Transmsission Through the Sutra Scrolls and Writings of Nichiren Daishonin?

It is a matter of right or wrong according to the Lotus Sutra and the doctrines of Nichiren Daishonin.
