Which design has the edge?

Ive going round in circles trying to get a header logo for a site im building and have finally got 4 ideas I can work on.

They all need a bit of polishing but im wondering which you guys think looks best.

I can obviously change colours and font sizes quite easily so any suggestions are more than welcome!

I'd vote for number 2, doesn't take up too much space and has the orange making it easier on the eye
