A lot of guys run lifts and love them. Lift kits can consist simply of shocks and blocks. Or on the other end of the spectrum, they can consist of top shelf coilovers, bulletproof control arms and torsion bars, etc. The ride quality varies a lot from one kit to the next. Generally, if it's a really stiff ride, it was designed for towing in mind. You want that stiffness if you have a 15k lb. trailer attached. Your half ton was originally geared more for a smooth ride.
My '17 3500 had a pretty smooth ride from the factory. And I did NOT want to lift it. I wanted to keep the stock Geometry. So even though I chose a bigger tire (295/70/18), I chose to try them bone stock and they fit! So I went in the opposite direction and I'm still happy with the ride quality. If your tires cleared with your previous suspension and you like the ride quality better, you could switch back to that set-up. Your suspension and drivetrain will likely last a bit longer without the lift also.
Just my 2¢ Like I said, there a great lift kits out there. I'm not knocking them. But they do cost money. Upfront and in the long run too. And not much looks cooler than 37" mod boggers on a truck with a 8" lift.
