"well like it or not there is a synthetic vs organic conflict, Bioware put it in there, it doesn't matter if there has been no evidence for it, it's there, Bioware may have screwed up, but it's there."

Actually, it does matter. BioWare can claim anything they like however if it is not in the plot then it does not count. Likewise, if the existing plot or lore contradict these these claims. What that amounts to is terrible writing. Good stories to do offer plot development from twitter.

Nevertheless, I can spin a negative for each ending.

Control: Shepard AI has tasked itself with becoming the pseudo-guardian of the galaxy and using the Reapers to impose this order. What assurance is there it does not eventually conclude organics are disastrous and enact a "cleansing" to make way for new life? Be mindful the Shepard AI is only the embodiment of Shepard. They are not one in the same and dissimilar to organics, can be tasked to repeat a cycle believed to be necessary. In essence, Shepard AI could become the Catalyst in ever sense of the term.

Synthesis: While the ending presents an idealistic utopia, we have essentially merged with the Reapers at their leader's behest. Even disregard how completely asinine and contradictory this is with the Mass Effect theme. How do we know they have not enacted some form of control? The ending suggests conflict is abolished. This is simply not possible given the racial mentality. Humanity alone will eventually war with itself. We have two thousand years of actual history to prove such an assertion. Therefore, some variation of control must be implemented, suggesting the Reapers have won.

Both Control and Synthesis suffer from not actually solving the abrupt theme BioWare created. Neither prevent future organics from developing synthetics that ultimately betray them and cause a supposed Singularity, unless Synthesis does impose Reaper control. You could argue the Reapers would act upon this, especially in Control but this assumes Shepard AI could perceive it a threat. Regardless, the aforementioned reasons all make both these endings equally as "wrong" as Destroy.
