You can't go wrong with AEV, ARB, Schrockworks, LOD, Warn, Orfab, RedRock Fab, & Poly Performance.
Rugged Ridge makes some that are a la carte; and Smittybuilt makes things that usually break pretty easily and rust at the welds.
I wouldn't waste time putting a brushguard on the stock bumper; the bumper is a weak link to begin with.
Take the time to look around on this site, Jeepforum, Expedition Portal, JKowners.com, etc. Don't rush into it. Get to know the culture, the features, the benefits of mods.
After all, one mod often begets another. A heavier bumper will cause the front end to sag --- now you've got to add a spacer on the springs, add a lift, or put a bumper on the back.
It goes on and on.
