In my first playthrough, I went with Boone and didn't try recruiting anyone else. I liked him because he may be one of the "good" guys but he was ruthless. His quest line and the things you learn when conversing with him are really well written and you actually empathize with him, in spite the fact that he chose to Spoiler kill his wife instead of letting her be a slave. I also like his insta-hate when members of the Legion are near. In my current playthrough, I chose him again and fixed ED-E as well. I've also installed the mod 'Unlimited Companions' so I can recruit more people without having to dismiss someone. Haven't recruited anyone else yet though. Which companion do you usually choose? Who did you like the most?
