Gun fit, cheekpiece height and butt pad positioning are very personal things and vary enormously depending on the user's size, stature, positioning, style and the shooting position. Some will find the standard and the CS stock mentioned totally fine, others not. The ideal would be for a stock boasting adjustable cheekpiece and butt pad. I'd guess the vast majority of us are shooting "compromised" set-ups, as opposed to ones that fit us perfectly and, therefore, may not extract the best performance from our guns.
