My son plays in the SCIAC with both of these teams and was also recruited by both. Academics have already been mentioned...top notch at both. The CMS campus is a little nicer especially the new athletic building. Coach Walk at CMS is a really good guy. I would say Pomona usually fields a better team but it can easily flip flop any given year. My son knows a few players on both teams and they all seem happy and no complaints. As strange as this sounds CMS does have more of a party culture which includes school sponsored parties with lots of drinking. Really you cant go wrong at either one.
