Generally, older suburbs seem better than new ones. Those that retain their original village character are also good.
Around here that means residential streets laid out in a grid as opposed to cul-de-sacs, and smaller commercial areas more widely dispersed instead of huge ones concentrated along certain routes.
In short, any place built-up after the 50s is not worthwhile to live in.
Specific examples around here: Irondequoit, Brighton, and some sections of Greece are okay. Webster, Henrietta and other parts of Greece are not. Suburbs that retain their original village character are: East Rochester, Fairport, Spencerport, Brockport, provided you're in an older section of them and not the mini-sprawl that surrounds them.
