14-24 mm vs 16-35 mm

Which one to buy. I plan on using it with my D4. I love the 2.8f on the 14-24 mm but I see it is an accident waiting to happen. Without filter protection I know I'll scratch the lens. But if it is totally superior to the 16-35mm i guess I'll take the gamble.
Not being able to use "screw on filters" could also be a pain.

With a D4 I know I can get by with a f4 lens, but is the benefits of the 14mm f2 worth it??
Has any one used both and can give some direction as to what to do???
