The Quarians started a war in the middle of a reaper invasion only because they thought they can win it.
False. It was either before or hours after the beginning of said invasion, not "in the middle of". The second half of the statement says nothing and makes no sense. Who in their right mind starts a war that they think they will lose?
They wanted this. The Geth didn't. For me the Quarians are the aggressors.
Yeah, they did, unquestionably. As for the geth, I'm sure they didn't want to be punished for occupying and squatting one someone's planet, then trying to make it unlivable by surrounding its star with a Dyson Sphere, but it's a pretty easily foreseeable consequence of said action that you will be attacked by said people for doing so. That's like saying that the people prosecuted at Nuremburg didn't really want war, they simply wanted non Aryans to lie down and die in their camps as their lands were used by the Ubermensch. No one wants war if their objectives can be acquired by less destructive means, the geth simply thought they could hold their ill gotten territory without one and use it how they saw fit until the end of time.
Whats your alternative for the quarians? Diplomacy? Peace envoys? The Council already tried that one. The only "peace" acquired was the pieces of said envoys they got back in return.
And then they doomed themselves in the events in question...it was their own stupid fault. The Geth did try to escape, but Gerrel wasn't about to let that happen.
No, it's your fault for handing the geth their Reaper code and then intentionally withholding information from your quarian allies about their newfound vulnerability out of spite or incompetence. Of course Gerrel wasn't going to let the enemy retreat and continue future resistance if he could prevent it. He's a competent commander, and that is tactically unwise.
It's also yet another example of the flawed "it's not my fault" argument that litters this thread. Why is it so hard for you to own your decision in a video game?
I addition, I simply get more utility from the Geth. They provide one of the most advanced fleets aswell as infantry. And they cannot be hacked while organics can be indoctrinated. So the Geth it is.
No you don't. Utility is measured mathematically in war assets, and the quarians provide 875 to the geth's 815 in ideal circumstances. They can totally be hacked. Admiral Xen makes them perform a bloody dance number, and any character with Sabotage such as Engineer/Inflitrator Shepard, Tali and the characters within the canon multiplayer can hack Reaper upgraded geth all the time.
