I had my eye on some similar stirrup-style nerf bars (n-Fab) for a long time. When I finally got them I hated them. Small stepping area and my feet kept slipping when they were wet. My wife completely slipped off of them once and smashed her shin. Needless to say I was ordering something different the next day.
Yes, AMP is expensive but you get what you pay for. They come down lower and farther out than hard-mount side steps. There are other ones out there that may save you some coin. Also, if you go this route make sure you keep them lubed so they don't bind. The motors aren't very big so it doesn't take much to limit travel.
Depending on your budget there are a lot of options. A good place to do some window shopping is Runningboard Warehouse (

I had Raptor ovals on my last truck and loved them. A little lower than the OEM height and the step pads had plenty of grip, even in the wet and the mud.
