None of the plug & play (lux, mtec, etc.) or HIDs come close to OSS. They need to be custom installed but are evenly distributed to each ring unlike the others. Plug & Play only look good when it's dark and looking straight at them. No comparison IMO. Of course they are much more expensive with installation.
