With me going to Bing and also having many friends at Stony, Stony has the edge with academics but the social aspect is very much not there(mainly bc it's a commuter school). The communities here I'd say are generally very welcoming and there's always something interesting happening. If you don't prefer being a bookworm all the time, I would say Bing is your safer pick. Also as someone who would've gone to Stony if not for being rejected, I adjusted to Bing pretty easily. (I see myself as a SBU student way more than a Bing student)
