I think the spectrum is the RGB , and the core is the other one . Pretty sure the only difference is the RGB . Looks like the core has a blue default . Same price though as far as i see . <| sep |> HA and Apen ? Or HA and CD ? <| sep |> One thing to consider is education . I personally believe that Chicago public schools get a terrible rep and that they actually do a very fine job . The key to your child succeeding in CPS is that you must 100 % be on top of their education . Getting into the right elementary school is extremely important , but it doesn ' t stop there . Make sure your child is doing well in school and getting all their work done and become involved in the PTA . If you stay on top of your child and make sure they take education seriously they will be ready for the extremely stressful high school enrollment process . Getting into highschool was honestly more stressful than getting into college for me . That being said , growing up in Chicago was a magical experience that I wouldn ' t trade for anything . If you ' re serious about moving here you MUST do extensive research into the school situation .
