They are not comparable.

K glass is glass that has a reflective coating that helps reflect heat, making the window more efficient. All new windows should have this (or a version of it) as standard.

Leaded glass is where lead piping is glued to the glass for aesthetic purposes.

As mentioned they are not comparable items.
