The advantages are considerable!

perhaps it's because of long exposure to c-style short circuiting logic; but i generally find the SQL NULL behaviour heavy and hard to tame.  any non-trivial _expression_ quickly becomes a tangle of special cases to handle NULLs, and choosing the exact operator/cast function is a nightmare.

can you point some references that make it all "click" and see what i'm missing?
