The Minutemen: Still developing, but is literally the Commonwealth itself arming and uniting under a common cause to liberate itself

The Brotherhood of Steel: Strong and powerful, but definitely does not have the Commonwealths best interests at heart along with everyone's support, and has no plans to stay long after the ending

The Railroad: A Good goal and cause, but one that only benefits one kind of people, with no plans for everyone else

The institute: Advanced and could do plenty of good if it wanted to, but has their mind set on restarting mankind below the surface without care for those above them, and has already hurt the Commonwealth so much

I think this is easy
