Just as with any town it may have more or less what you are looking for. Raritan is a great commuter town I lived in Neighboring Bridgewateer for sometime, and as mentioned schools are outstanding. It has a great mainstreet and access to just about everything you need large malls in area great parks all the advantages of a small town but with everything within a 10 minute drive.
Best thing about raritan is you don't need to drive, Mainstreet has it all. + walk to the train They are strong in tradition with Parades saluting a local hero. Everyone is different in their needs and if taxes is what has you worried maybe the cost can be offset by the easier access " walk " to the train as compared to buying a parking pass which can be expensive anywhere.
If you like to talk about the area feel free to contact me my office is right down the road from there
