I accept that we follow different traditions with different ways of doing things. In OUR tradition any sensei who broke their uke would be considered to have no control and I think would quickly find themselves getting a talking to by the other ranking instructors. Being raised in this type of aikido is why I am not as impressed by people who can launch their uke as I am by people who can put uke on the ground without uke knowing why they got there.
To be truthful I'm more impressed by to people who can do both depending on the situation (i.e. uke's skill, threat level, whatever)
