Planes are easier because they can glide. Cost is cheaper. The simple small ones.

Heli's are rocks and they drop unless you can auto. More costly.

Heli's are more harder to master but the rewards at the end pays off.

I heard planes are more relaxing. Yes Helis are like balancing a broomstick on one finger. You are always moving your finger to keep the heli steady. Planes you can take a nap onces it up in the air.
