the question is real obscure, but levelling is all about looks since a level riding empty pickup is going to squat under load
do you need a lift? likely no. on average most 4x4s have plenty of ground clearance.... more to the point, do you NEED bigger tires????
THAT is the question. No one does a real cost, performance, reliability, comparison of stock vs lifted real world results.
I'll say stock would be fine for 95% of those who lifted their trucks. And for at least 50% of those with lifted trucks, stock would be more reliable.
Lifting and bigger tires corrupts all that expensive R&D the factory does to build a reliable truck with great warranties.
Lifting, bigger tires, regearing, all add capability for sure.
They also add stress to the stock components leading to more "upgrades" to retain reliability.
Yes, moderate changes lead to moderate shortened life of the stock parts. I know I changed front u-joints more often with 33s than with stock rubber.
I am now back to almost stock spec because I like reliability, reduced maintenance more than the ego thing of running a lifted truck which really does nothing better than a stock truck.
I'll get flamed by a few who love their 37s but I have yet to not get to the same place on stock rubber.
