I guess it depends on where you live and what you do with your truck.
I use mine for work. I'm always in mud sometimes up to and past the frame with a 6" lift, and the country I run in has a LOT of deer and moose so most guys run light bars and bush bumpers for extra protection and light. It's standard procedure around these parts.
For a city truck, or pavement princess that doesn't see alot of miles or tow the lift and light bars aren't really needed IMO other than for looks. Stacks have their place too. Hood stacks are great for saving weight on a drag truck. .

There were a couple days this year my truck was the only vehicle in the neighborhood besides the tractor that could negotiate the road back to the house.
