Are Marines overrated?

First, I just want to say I'm not trying to bash, I am completely serious about these questions. How come if someone ask if Marines are better or tougher, people say marines but have no facts to back it up and instead say some thing like "First to Fight" or "Every Marine is a rifleman"? They say the Army is poorly trained but if you talk to anyone who served in the Army and Marines they will say the training is similar but the Army has better equipment. If you have people that served in both who say the training is similar, then why do people act like Marines are supermen? Another thing I don't get is why does the Marine Corps spend so much on its PR when it could go to something more usefull such as training and better equipment? What does MARSOC contribute that no other special operations group have? What kind of missions do they go on? Didn't they get kicked out of their first deployment? During the Battle of Fallujah, why didn't the media mention the army soldiers that took back the city when the marines were the ones that lost it? Infact it seems the media does that a lot. Why do people think the Marines are the first to fight when they never were the first to fight? Army Special Forces and CIA SAD teams were the first ones in Afghanistans not marines. During the Invasion of Iraq, the invasion was spearheaded by the Army and Marines and from what I heard the marines were going slower than the army and it slowed down the invasion. So would you agree that the Marine Corps is overrated? Is there something I'm not getting? Everybody says their jobs are different but from what I hear their jobs are the same.
