First picture is Episode 5, Mafiya, all three times mastered:
Second picture is Episode 5, Vory, mastered two times:
As you can see, for episodes 5, Vory and Mafiya use mostly the same equipment. The two jobs in Chapter two that are different:
Help "Plan" The Next Attack: Vory tier uses Forest Camo Suits while Mafiya uses Artic Camo Suits. I think the Vory tier is a bit better in Episode 5, so I would go with Vory and sell off all my arctic camo suits.
Episode 6 is a bit different - it uses ALL new equipment:
Mafiya Episode 6, completely mastered:
Vory tier is very similar - it is all new equipment, episode 6 only. So, once you finish off the previous episodes, you can sell all your old equipment except the stuff you need for Episode 6 (save the pieces you need to collect the best armor and weapons in game).
