Personal preference.
I only fly fixed wing stuff and I'm using #30 on the Y-axis and #20 on the X-axis, since I like a bit more "stiffness" on the elevator but want my ailerons to be pretty light.
More importantly IMO, you also have to take into account what sort of clutch strength you want. In my case, I wanted as much clutch strength as possible but still wanted the stick to reliably return to dead center when I let go of the grip. After I swapped in the 30s I adjusted the clutch just so that it would neither overpower the spring nor be overpowered by the spring.
I found that the clutches can pretty easily overpower the springs, even the 30s. Meaning if you apply too much clutch, the spring won't be strong enough to pull the grip back to a dead center position. And just like with a dampener/spring combo on a car or bike, you want both elements to work in unison, and not have them "fight" each other.
All that said: I'd recommend setting things up in a way that feels good for you and then try it out for a few days. Instead of staying up all night, constantly fiddling with springs and clutches, looking for a "magic" setting. I've done that and that "magic" setting doesn't exist.
