They all can pretty much kick most every enemies ass efficiently. Other than that, he is a moody prick that makes you have to worry about where you take him. He’s a hellofa shot and has a mildly useful companion perk. All three are highly combat effective but Boone takes my top spot because of his ranged capability and because he’s got probably the most useful follower perk, (IMO) spotter. My top three are Boone, Veronica, and Lily. Who is the best companion in Fallout New Vegas?
The easiest way to gain these points is killing Legion with Boone as a companion.
In order to get him to open up to you about what happened at Bitter Springs and begin this quest, you need to gain 5 ‘trust points’ with Boone.
Trigger: Boone probably has the toughest Companion Quest to trigger.
