Yes, Jung's/Berens' descriptions of the functions are more accurate/correct (but less precise) than SSS and mainstream Socionics' definitions of information aspects. Jung observed people's behavior and described eight (2x4) distinctly different cognitive processes. Aushra then tried to combine Jung's theory with information metabolism, so she introduced information aspects. These had to correspond with Jung's functions. However, Te/P (for example) is problematic in both SSS and mainstream Socionics theory.
It's a comparison of apples and oranges.
