Disney is good if you have little kids even though the prices are complete rip off. I've been to both Disney and Universal several times. Universal is a much better time by far.
I never went to either before turning 50, I can only imagine Disney for kids is mind blowing. For me, I liked Universal Hollywood over Universal Orlando. The tour through the backlot to see many of the props I've seen in movies was worth admission alone.
Disney World was better than Disney Land although I did like the river boat tour in Disney land knowing it was there when I was a little kid. So for Nostalgic reasons it was cool but Disney World was by far better overall
