I actually forgot Zywoo. He might knock Autimatic off the current top 5 list to sixth. Then again I may have overrated Woxic.
Either way I think in a jumble the current best are Device, Simple, Autimatic, Zywoo, Woxic, Guardian, and again Oskar if he finds it within himself.
I would say that Autimatic, Zywoo and Woxic still have the most to prove out of all of them.
