Let's not derail the thread with finger-pointing; regardless of possible hypocrisy, it's never a crime to ask someone for evidence for their point of view.
My own feeling is that Void Sentry wins, for the reason stated above: SBP's main weapon is his punch, and Void appears to be able to recover from any kind of physical attack. Now, to be fair, SBP's punch does contain a high quantity of WTF factor, but until we get scans of him actually punching an opponent of this calibre into another dimension for BFR, or punching a hole in someone's soul or something (really, if this happened at some point I would be elated), I don't think it's possible for void to lose this.
