I live in OC. There is crime and gangs in some parts, but others are just fine. The only guns I have ever heard, ever, in over twenty years here is when I'm at the range. Fiscal problems are severe, as in many, many other states, but there are serious efforts to resolve them, more so than anything in the last decade. Whether or not they succeed will remain to be seen. If you've lived through Albany at it's worst, this is slightly better right now.
Housing prices will stun you, compared to Syracuse. You need to figure your increased mortgage payments against your raise; I know folks who did that and it queered the deal.
Weather will equally stun you. Compared to upstate NY (I did undergrad in Buffalo), this place is unbelievable. A really, really cold day is 45 degrees. No snow and continuous sunshine.
Other amenities include glorious supermarkets filled with fresh produce year round. Tons of cultural opportunities.
Above all, in your area, you will be in a place that is thriving and exciting, rather than the struggles of upstate to remain viable. That counts for a lot in my book.
I still love NY--going back to the city next month--but I'm very glad I moved here.
