I have this question, and i would like to know

why most advance programmers like to design using code not designer ??

which better to design with code or designer??

I like to use the designer because :
faster,
easier
you can see you deign and modify it faster and easier.
help me to improve me design as i can see it and would help me to visualize it more.
much less code as i don't want to worry about creating all the widgets and set their attributes using code.

Please in light me with why code is better than designer, or why most advance use code and not designer ??

Thank soo much
