Wow, it's hot in here...
After reading through all twenty-two pages, I'd still pick Synthesis most of the time - depending on my Shep, of course. While I agree imposing a singular form on all life would never have been a choice I'd make if I had better options, but I don't think Control or Destroy are better options, FWIW.
Taboo makes some strong points about interference and how the Geth don't play into his/her decision because they are dead by that point and perhaps, if I only had EDI to worry about, I might choose differently. But that isn't the case in any of my Sheps. However, the suggestion that choosing the Quarians over the Geth, as a numbers based thing, well, we know there are 17 million Quarians in the galaxy. We know there are several billion sentient geth programs in the consensus. I'd still have to side with the Geth.
I also agree that exactly zero of the 'choices' Shep is offered is anything but morally - and ethically in my purview - reprehensible. Unimaginable power, but no itty, bitty living space? I'll pass. Genocide because it's convenient? No thanks.
One more thing, even if one considers anything the Catalyst says as false, for which there is no in-game support, the Catalyst isn't the only one who states synthetics will always turn on their organic creators. The Prothean VI iterates this earlier in the game. Javik iterates this much earlier in the game. Every cycle has seen the eventually creation of a synthetic species, and said synthetic species inevitably comes to the conclusion that organic life is inefficient, dangerous, and the antithesis of order and so must be eliminated.
Honestly, supposing that somehow *this* time, *this* cycle will somehow manage to avoid that - even IF Shep managed to work out a peace between the Geth and Quarians - is the epitome of hubris. The extreme arrogance, the massive amount of pride it would take to claim that the beings of this cycle are somehow so much BETTER than any that lived before and so, of course, they'll be able to avoid organic extinction... Unless it's more that Shep is saying, 'well, I'll fix it for now and to hell with the future, it's someone else's problem'.
Takes a lot of hubris to say Shep can control the Reapers as well, though I suppose a point in favor of it is that Shep isn't indoctrinated - despite a very good theory that came about AFTER the fact and with zero backing from the devs - might give Shep a little less arrogance in choosing Control. That said, I haven't played a Shep yet that would be inclined to take over not just another sentient species, but actually thousands of sentient civilizations. That's just creepy, IMO.
I have played through all three variations, made all the choices, including seeing the breath. I don't feel 'good' about any of them, but I've picked Synthesis more than the rest.
