There's at least one significant difference - a null variable returns 'X' from vartype(), but the last type the variable had before it was assigned a null value from TYPE(). Also, if you pass an expression to vartype() with an illegal expression in it, it generates a VFP error appropriate to the illegal expression (syntax error, data type mismatch, etc.); TYPE() simply returns 'U'.
