Yes, the Jallib-Ossir pair is different from the Ossir-Air pair. But Ossir consistently performs well only with Air, and perhaps with Helmar.
As for Ossir-Jallib, this is a pair for those who like it; that is, it is very interesting to play with Jallib here, of course, but Ossir is stronger... much stronger.
