Seating tickets or GA tickets?

Going to see the Foo Fighters in October with my parents (I'm only 14...) and I have to decide whether I should get seating tickets or GA tickets. I might get seated tickets because I'm short and I won't be able to see them if I do get floor tickets and I'm claustrophobic. But I want GA tickets so I can see the band easier. I might get to the concert around 5:30 pm and it starts at 7pm. I think I might have to get seated tickets but are GA tickets as bad as everyone says it is?
