I don't think you're going to hear any opinions from people that have owned both the kits. Usually people just pick one, buy it, and vouch for it.
If the user bought the Racingline one, or owns one, they'll likely vouch for it and most likely will not have tried the SBD one as well.
I'm no different. I own the SBD one, have never tried the Racingline one, and will vouch for the SBD one.
