Landcruisersteve has a good thread comparing the 2 (Warn and All Pro). He owned both and liked the AllPro more. Maybe check out that thread. Personally, I want a bumper that can accompany a winch and lights. I don't care that the bumper is super strong. I expect it to be stronger then the stock, absorb some impact, but I do not expect or desire it to be so strong that it escapes the impact unscathed. If it's going to bend the front end in, just let it go. I don't want to have a good bumper but a crumpled front end. The AP bumper is slim, light, and has great approach angle. It's also cheap enough that I have money left over for other stuff. Fits the lines of the FJ pretty well too.
The overall look is fine for me with the WARN, and the one thing I really liked is the fog light mounts that were REALLY low, much lower than others, which is the idea for fog lights. Even being low, they were protected.
I guess I'll review the others, to see if they can be adapted for really low fog lights. The ARB looks like it would be difficult to do. I'll double check Demello.
as for the ARB being air bag compliant, that just means they crashed a FJ and the air bags went off, you could duct tape a log to the front and it will do the same thing. the sensors are g force activated and attached to the truck, not the bumper. Just something to think about.
