Whats your opinion on the Marines and Army?

Hey, I am a senior in high school and am attending college next year. I have been looking into and am very impressed in the rotc program. I have to decide whether to go army or marines though and I have heard negative and positive things about each. I have heard that army is uncoordinated and ran poorly and I also have heard that marines are just brainwashed jarheads. Obviously I know that these are ludicrous over-exaggerations but am curious of your opinions of the two branches and if any are more bearable because I do plan on putting in 20 years.
