My first guard on a truck was a Westin and it worked well. It was more of a brush guard than a full width guard. And all I wanted was a light bar.
I was about to install a Hunter bull bar on this truck but again, simply wanted something to hang some lights on vs. a real protection for the front of the truck. I ended up with an NFab light bar and I really like it.
Westin, Aries, Bully and Hunter all make fine guards. Good luck with your choice!
