They're the exact same kit, Sinister copied RCD's design. But RCD has treated a few members pretty poorly, so it's your choice.
I went with RCD a couple years ago because Sinister simply copied their design. I wanted to give credit where credit was due, so I went with RCD. But since then, RCD has mistreated some fellow members in regards to their injectors.
As far as quality, my RCD kit has been installed for about two years and it's still running strong.
