Only if you're farming for something from the 3-3 or 3-4 boss nodes (and 3-4 is a godawful map to try to farm; 3-3 isn't much bette from what I recall, but I cleared it about 9 months ago). Otherwise, it's not remotely worth it. Same for the world 4 weekly quest. At least the world 4 one can be done with a submarine team, which makes farming 4-1 and 4-2 viable. The odds of a sub team actually reaching the 3-4 or 3-3 boss is really low. Subs may be a potential way to clear 3-3 or 3-4 if a more conventional fleet isn't working well for you, since you only need to do it once but not for farming.

So yeah, the short answer is that the world 3 quest is basically never worth bothering with.
