I vote Reapers. While the Transformers will put up a better fight than anyone in the Mass Effect universe ever could. The Reapers' technology, such as the relativistic (near or approaching light speed) molten tungsten weapon, is more than a match for most other weapons. The mass effect (the in universe phenomenon not the games) technology may also give an edge. I'm not sure how reaper AI would interact with the Cybertron life-forms, it is shown in Mass Effect that they can indocrinate organics and directly manipulate Synthetics, not sure how that applys to the transformers. The Transformers will not go down easy though. The Reapers also posses the thought processes of both an AI and the millions of organics they are made from.

We are each a nation. Prepare yourselves for the arrival.
