All of them are pretty boring imo but I guess G.I Blues is the least boring. Though the amount of back-and-forth you have to do is pretty annoying and tedious

Like all of them, G.I Blues is the shit though. Birds of a Feather is a great quest but you have to have Cass killed to unlock the weapons deal finale which is stupid.

^ Yeah, even when I am not doing an NCR playthrough (so Cass and Boone will eventually refuse to accompany me), I'm not going to sacrifice a companion just for a quest. Unless I am doing an evil playthrough.

Fisto is the only reason for me. Just funny. I remember raising an eye brow when the bartender "misspoke" about the Protectron.

This technically isn't a quest, but stealing literally everything out of silver rush
