I love the Ergon GA3s for general riding. I've got a birth defect where various joints in my hand are fused, making conventional round grips not ideal for grip. I find that the wing shape provides a big squishy platform for my pinky to sink into and hold on well. I played around with the DMR deathgrips and chromag wax but have consistently come back to the GA3s.
I agree with the comment about the position of the wing having a large impact on the feel of the grip. It took me some riding and tweaking to get the roll angle of the wing in relation to the brake lever and grip right for me.
