Behind the neck barbell military press...?

Hey Mike... Last week I was in the gym using the military press station and was approached by a "gym aqatence". He informed me that he read that behind the neck press was good for you and that 70% of body builders also gave it a thumbs down. Is this true and if so what other exercise can achieve the same benefits?  Thanks a bunch and ps your videos are very helpful I. Making sure my technique is correct!!!
