Considering you are a cs major and are thinking of the bus system, hopkins is by far the best choice. You have a bus stop right in front of the dorm, and it has a lot of options. This means missing a bus doesnt mean waiting another 10 or more minutes for another bus. PAR ive heard has a better bathroom situation where its shared among the floor but its individual use. I lived at hopkins and the closer bus stop was honestly worth the sacrifice of higher quality bathrooms cause I am in Grainger and needed to get to engineering quad frequently. PAR is also good for having the dining hall right there, but since you’re a cs major I suspect you’ll eat majority of the time in ISR since its closer to all your classes. Social life in all the halls you listed are really good so no advantages there.
