I think being up 100 floors seriously offers the best views in NY. We also did Top of The Rock at the Rockefeller (which I also recommended) but from One World, you have disrupted views of all major bridges coming into Manhattan and Statue of Liberty.
We went mid November on a Saturday afternoon (2.15pm) and there wasn't really any queues. It was busier when we had finished with people coming up for sunset.
Be warned, it was $18 a glass of wine and $12 a beer! However, a must visit!!
