Calling on all of you with NYC touring experience yet again! Gosh I appreciate you guys! If I have to choose just one, IYHO, should we visit the observation deck of the Empire State Building or Top Of The Rock?

I was all set to purchase our advance tickets to the ESB last night & I went to (can I name this site? if not I apologize) Trip Advisor & read reviews & the majority of them all said that if you could choose just one, to visit Top of The Rock! Everyone claimed shorter lines, more interesting que, more friendly CM's and you have a great view of the ESB & Central Park. If we choose TOTR, we'd still visit ESB, just not the observation deck. I'm going to have my family look at both this week, but I'd really appreciate any advice from you guys!
