Tokyo Tower vs Sky Tree!!

Tokyo tower is a huge antenna tower!
It's 333m tall but when you go to Tokyo Tower you can't go right to the top, only about half way.
It was my first time to go to Tokyo Tower .
I've always wanted to go to Tokyo Tower but I didn't have much time to go.
When I went half way I saw a lot of buildings.
Tokyo Tower was built in 1958!
Next there's a tower that's being built that will be taller than Tokyo Tower.
It's called Sky Tree.
Right now it's about 400m high. When it 's finished the height will be 634m!
Which do you think looks better?
