I won't speak for Greg, and I do hope he pops up sometime to explain. But his quote was "Sway bar gooood."
I asked a few other experts that were at the TRR and they all had different options. I was left with the impression that's its really a personal preference, and each side has good reasons why to run with it or not.
If it matters to you, after 2 years and 40k miles of running with it, I am now without and I will stay without. I very much prefer the ride and handling without when combined with my mods. YMMV.
Great writeup by the way! The only suggestion I might make is that you don't need to actually "remove" the bar. Simply pulling one of the end links gets the same job done (driver's side in my case) and allows for even easier reinstall if you decide you don't like things without it.
