if it's "worth it" is a really personal decision. how flexible are you? do you like things neat (or quiet, or whatever) but it doesn't bother you if they are messy, or is it actually distracting, for example. how private and quiet your room is, how social you are (and how social your roomate is) all play a part.
when i was younger, i liked the social aspect of a roommate, but when i got older i just wanted to go home and chill out for a while an not have to make small talk, and not worry if that was rude. i actually rented a 2br myself, so that i could choose my roommate, being the one holding the lease, because i had become much more particular about who i wanted to live with. i ended up picking people to live with not based how how much i liked them, because you can think someone is smart funny charming fun etc and learn that you don't like to live with them, and instead ended up picking folks based on roommate compatibility, even if we didn't have much in common, and honestly that worked best for me.
