For subs, just running 2-3 (Orel Cruising) will get you there eventually, or throw them in the flagship spot in PvP. Grinding 3-2 uses subs as tanks so you could do that too, but since the point of a sub in that grind is for the sub to take the hits, it's not good for leveling a specific sub.

For non-subs, 1-5 and 3-2 are your best grinds that you're going to find in the early game. There are several guides on this wiki about how to use those maps for the best XP gains.
