Pinch style is easier to manage if you don't have to hold the transmitter. Stiffer springs also make it easier to separate left/right from up/down stick movements no matter which style you use. Look at old pictures of Hanno Prettner's (and others) position while flying. The transmitter tray is very low allowing him to grip the sticks from the top and use the greater resolution of control motions from the shoulder instead of from the wrist or three joints of a thumb.
