Bonnet protector is pretty useless, it only protects the leading edge and about a foot up the bonnet from chips. Your bumper will still get chipped/pitted.
I have a tailored Robco car bra, and it doesn't look too bad - but both the car and the carbra are black. However, it's a bit of a chore to use. I only use it if I'm travelling out of the city. They're not really practical to use all the time.

To fit it, you open the bonnet and slip the pocket over the bonnet, then close the bonnet and stretch it over the front bar. It attaches with adhesive velcro tabs, and well padded metal bend tabs that hook into the wheel arches. You will get a sweat on the first time you fit it, since it has to stretch a little. The car bra has to be warmed up in the sun when you put it on. Ideally the car has to be spotlessly clean and waxed when you put it on. And if it rains, you have to take the car bra off, you can't let it dry on the car.
It does have flaps for the headlight washers to pop out of, but I still avoid using the washers while the car bra is on.
Another good thing about the Robco one is the bug protection for the vents, and it has wind deflectors that send bugs and debris over the top of the car. Last time I drove to Canberra with it on, I didn't get a single bug splatter on the windshield. And the car bra mesh on the radiator intake was full of small bugs that it prevented from getting into the radiator.
Clear car bra is awesome since it doesn't look dorky, and you don't have to worry about taking it off/putting it on, but if you have a dark coloured car, you can see the car bra as it makes that area of the car look a little milky. On a lighter coloured car, you don't notice it unless you look really closely.
