I got my last set their for my last truck (Raptor ovals for my F-250) and loved them. Solid, sturdy, and stood up to a lot of desert trails.
Everybody has their personal preferences so I'll only provide a couple of observations:
1. My F-250 was taller than my 1500 and my wife was fine with the nerf/ovals I had on that truck (she's 5'4").
2. My dad has had AMP power boards for years (at least 5) and after a few adjustments after initial installation (and occasional lubrication) they are still working fine today.
3. I had always wanted a set of n-Fab bars. After I finally got them I learned that I really don't like stirrups. You had to look to make sure you were stepping on them and when it was wet my foot would slip off of them regularly (my shoe size is 13). My wife and kids slipped off of them once in the rain getting into the truck and the look my wife gave me told me everything I needed to know.
Tons of styles, models, and manufacturers to suit every need so you be able to find what you're looking for. Good luck!
