So I beat the game last night. My feelings are below in transparent for spoiler protection.
[spoiler]
I decided to choose option C. Deathwish, because I couldn't kill Micheal and I didn't want to kill Trevor (even though he was my least favorite of the three) and I had a feeling that if Franklin called both of them up and told them what was going down they could forget some stuff up and make it through. Well as everyone else who picked option C knows, they do. But honestly, I don't know why anyone would pick the other endings aside from just sheer curiosity. Unless, (which this is totally possible and not in bad way) thought that C would lead Franklin to his death and while C ended well, I was content with the ending and glad I could still play as all 3 characters in free roam I looked at the other 2 endings on youtube and they were just kind of meh, in my opinion. [/spoiler]
But again, that's all in my opinion and I have no problem if you think differently. Please feel free to tell me what your thoughts were on the ending since I am honestly curious.
By the way if you want to know my favorite mission it's either: [spoiler] The Jewel Store Job, Did Somebody Say Yoga? Caida Libre or Derailed [/spoiler]
