Instead of the best, I am going with the most impactful one for me. It is a GIG called Dirty Biz.
The missionis to get in into a building, and geta BD about killing a 12 year old boy, who is the son of a televangelist, so they can get closer to the killers. I went in, killed the guards and wenr into the office, where I found a middle aged man, with his son watching a BD. I interrupt them, and ask them about the BD. To my shock they do not know first which one I am looking for, as they have multiple ones with kids getting killed.
Of coursethey are trying to push away their responsibility. We are not making them, just selling them, there is a demand for these BDs and if not them, someone else would do it blah blah blah. When finally I get the BD, the quest says to leave, but I turn around and kill the father first. The son cries out for his father, but I shot him in the head as well.
Thinking back, should have only killed the son, and let the old dude alive. That would have been a more poetic justice.
Anyway, I have left the area get the money etc, but after that I had to take a break. It showed me how dark this world can be.
