Which hair relaxer is better...Motions, ORS Olive Oil (in the green box) or Hawaiian Silky?

My hair is typical kinky (4a) Afro texture hair. I have tried motions, it works well, but burns like hell. I've heard good things about Olive Oil relaxer and I don't know much about Hawaiian Silky. I wonder if it lives up to its name though. It would be great if you have first hand experience using any of these, but all feedback is welcome! THANKS!
