Well orel is basically used if you're really low on resources and have the time for it as well as clearing weeklies for aircraft carrier and transport ship kills with a side of gaining a lot of experience for your subs. I've never personally leveled my subs at 5-3. 2-2 is faster for transport kills and 2-1 is faster for carrier kills if you need it.

Before orel though subs are neccessary for 3-2 grinding as they tank all the hits besides closing torpedo. It's pretty much one of your first grinding areas for BB or CV after 1-5.
