I haven't played all of them or finished many of them, but so far, the group I would like to hang out with the most would be the Dawnguard. Isran seems like a strong leader, and some of the others are quite inventive and creative. Dawnguard offers some of the best weapons and armor. I also like the Bard's College, the Orc Strongholds, and Greybeards as far as groups of people I would like to hang out with.
On the fence about College of Winterhold- too cut off from society and weak leadership. I like a lot of the Thieves guild members, but their goals and missions are too much about being thugs.
Not crazy about the Blades just because Delphine's personality is annoying. And Companions are too Nordy and not that interesting to me. So proud of themselves for just being able to kill.
Most of the evil factions I have a hard time getting into, but I want to bring myself to be a vampire or finish the Dark Brotherhood on a playthhrough sometime.
