Yes, Having less contact area will increase the chance of stripping. I use them on lower torque applications. I would not use one to set a pinion grub screw. Also sometimes I'll place the bolt on my hex driver first then take it to the hole, you can't do that with ball drivers. I use the ball-tip set from bondhus too.
I prefer to have both on hand, but in a jam I'll take Non-ball.
