I can't comment on brands but I feel I should point out that the mounting of bull bars and brush guards on our WJs aren't very sturdy. These things are more for looks as opposed to use. Many people feel brush guards actually cause more damage to the vehicle when in a front end collision as opposed to no guard at all.
That being said, I'd look into adapting the brush guard's mounting points to work with the Fawkes
products. This will make it much stronger. Also, check out this thread: High mount bull/safari bar revisited
I'm not positive how the brush guards mount compared to the bull bar but it should give you some good ideas.
