I'd say it's worth it at your point in the game to crack on with the main plot and get to Diamond City. There you'll get a few more companion options if you want, one immediate in Piper, and if you continue with the main plot in town you'll get the quest to meet my favorite companion. You can keep on with the main plot till that companion wants to "investigate the house" in Diamond City because once you do that it'll start events that lead to the closing of Act 1, for whatever that's worth.
