Progress Tech and Agency power Sway Bars the same?

After researching ive seen people say that these are basically the same thing. that agency power uses progress to make these. Is there truth to this? is there any difference? Because im finding agency power front and rear sway bars for cheaper than progress tech. So what are the differences besides the paint and price if any? any personal experiences with either? if none i would rather agency due to price obvisously, and i would prefer a white sway bar. Looks better IMO. Thanks guys
