Spin training is all about building confidence, it helps with the overcoming shock of having the aircraft entering the incipient phase in a stall plus drilling the reaction required to exit that error - for me flying needs a planning or training to overcome fear and to create the necessary automatic responses in an emergency. I will personally vouch for this having lived through a bad landing accident that once the OMG moment passed [ie "this is not a drill'] looked back into the cockpit to see the stick jammed in my belly, full opposite rudder and my hand pulling the throttle closed. The aircraft picked up the port wing and then just dropped on the ground in a three point position perpendicular to the runway center, motor idling - there was NO conscious decision, it just happened.
This was a product of doing incipient and spins with my first instructor until I believed I could handle the situation. I agree a stable spin in a lot more comfortable than deliberty dropping a wing in a stall unless the door blow open in that spin - story when I am drunk enough.
There is no substitute for beign drilled and drilled and confronting the thing you fear, remembering fear is controlled panic where the fear keeps you safe and the training allows you to control panic.
All aircraft will drop a wing and not to exposing all pilots to it is just sticking heads into the sand and as the aircraft that fly in the sports category change in performance it could be a nasty shock for someone told that spins are not an issue in this class of aircraft.
Hope this makes some sence
