Saren and the geth VS The illusive Man and Cerberus
Commander Shepard's biggest enemies besides the reapers are at an all out war. Who will win!!
Uhhhh that's a tough one.
I will put my money on Saren&Geth. While both parties basically represent same level of commitment Geth have one major advantage over Cerberus troops. You can make Geth from pretty much any scrap metal, you can't produce humans (at least not in the fashion machines are made). And everything what Cerberus stands for in ME3 is abominable from the start. Kidnapping people and turning them into automatons. Saren&geth look like galaxy saviors in this one.
Saren and the Geth vs. TIM and Cerberus. Both are mere pawns of the Reapers.
Counting numbers, it's Saren, hands down.
Counting Tech...... hm.... the Question is ME1 Geth vs. ME3 Cerberus, or both ME1 or both ME3, meaning Reaper Tech augumented Cerberus and Geth Troops. Otherwise they are not compareable.
The ME1 Cerberus Troops were insignificant in numbers and just humans, while the Heretics are Software, capable of Hacking anything Cerberus has to offer and the weapon platforms can be build and replaced quite easily.
So from an ME1 perspective, Cerberus would have no chance.
If only Cerberus would be on a ME3 level, it would be exactly the other way around, as the Reaper Augmentations uplifts them way beyond Geth warfare capabilities.
So I take ME3 Cerberus and Reaper Code enchanced Heretics and......
Saren would win. The bigger fleet, way more troops and even with Sanctuary, The Heretics replenish faster. If you do not destroy their server nodes, they do not die as they upload themselves if their platform is destroyed. This is a major advantage, as they are adaptable and capable of learning, improving their strategy. And both take no pity on civilians or other combatants to reach their respective goal.
What do you think?
