King's vs BP-51's

I found this Filthy Motorsports video quite helpful in seeing the differences between shock brands and types.

I have been running Kings for several years, have them on both my 4th and 5th gen and couldn't be happier.
This video pretty much nails it as far as the BP-51 (check out 12:30 minutes into the vid).
I also believe the Raptor shock by Fox (cut away shown in video right after the BP 51s) is not indicative of their whole line, I'm sure their 2.5" is actually a 2.5", but I have also heard of their lacking customer support. I don't actually have first hand knowledge, and won't trash talk them, because there are plenty of happy Fox owners, and the dual adjustment feature is intriguing.
Ben at Filthy is the real deal as far as customer support. Ordered my last set of COs from him. He will actually call you and go over your order and with you to make sure they have them built right for your particular set up and needs.
Micah at DownSouth Motorsports in San Diego has been good to me as well.
I've also heard Total Automotive Performance in Vegas has stepped up their game as far as putting kits together and knowing their stuff. I have had great luck ordering other items with them as well.

This may have changed, I was looking at these options when the BP-51s first came out and they where setup for use with the heavy as **** ARB front bumper. They would have road like a dump truck with stock weight.
