Is leveling a stock truck of value?

Sorry to bother the forum with novice info.

I don't really see my truck not being level, but maybe side by side with another leveled rig, I'd notice the difference. Is there any value to leveling the front other then aesthetics? How high do I want to raise the nose? I think I saw someone say "1 notch up will do."

I'm looking at simply getting new shocks, looking at Bilstein 4600 or 5100's. From what I gather the internals are the same. So that leads me to ask about raising the nose a bit.

 

You can adjust the Bilstein 5100's to level it. Leveling will also allow a slightly larger tire.
