Similarities and differences between the priesthood of all believers and the LDS priesthood

In the LDS Church, all men and older boys are encouraged to obtain the priesthood. Women are also encouraged to receive ordinances in the temple, which Joseph Smith described as entering into an "order of the priesthood" (see [1] ). Lay men and women have duties similar to ministers in other churches. This seems quite similar to the idea of the "priesthood of all believers" or "universal priesthood" practiced in other churches, in which it is believed that all believers have the priesthood. Its organization seems to be more informal than the priesthood in the LDS Church. What are the similarities and differences between these two concepts?
