Destroy. The geth and other similar synthetic life were, indeed, a big sacrifice to be made, but if nothing else, they proved that there can be peace between synthetics and organics. The reapers would never return and this alone is worth it. The other two go along with the goals of some of the main antagonists of the series (TIM and Saren).

Control leaves too much power to one man and, of course, "absolute power corrupts absolutely". Regardless of whoever is put in control of such a vast and powerful force, if they were to ever to use the reapers to destroy once again, it's back to square one. Even Shepard is corruptible.

Synthesis just didn't seem right. This is a huge decision to make for the galaxy with absolutely no input from others. It also eliminates some of the diversity across the galaxy; this is something Javik specifically said was one of the reasons his cycle failed in their fight against the reapers.

Really, I feel what's most sad is that we aren't really shown the consequences of each specific decision and that we have to make up the possible effects of our actions. And no, the presence or lack thereof of EDI aboard the Normandy does not really count as a consequence.
