I had mine sitting in the garage for years and finally decided to install them (mine are also aftermarket). Huge difference getting in the vehicle, especially in those tight parking lots. And a bonus is that you aren't dragging yourself over the left bolster of the driver seat, which saves wear and tear on that (which is a definite weak point of the interior).
The OEM side step are too close to the body. Makes it difficult to step on and twist into cab.
I installed Raptors from a group buy so the price was right. It mounts a couple inches from the body. Easy to step onto and then into cab. Disadvantage is that being mounted couple inches from the body makers it easier to soil your pants leg.
My Westins, like Raptors & others is not as close as the factory one. But yes, on the pants leg dirt. Kind of forces me to keep the truck cleaner, since as the years pile on remembering to avoid hitting the bar is the harder option.
Of course I only do it when wearing dress pants, which is not very often.
