				Which is a stronger flux, borax or boric acid?  Are there any other notable differences in the way they work between the two?

				All I know is that 20 mule team borax works.  I never tried anything else.  Some will crystalize at the bottom of the bottle, just pour the liquid off and it works.  This stuff is cheap.

				borax: Na2B4O7
boric acid: H3BO3
they are not interchangeable and not the same.
