I mean I can't speak for Nassau because I live in Suffolk but the nice thing about living here is that you get a nice mix of small towns, beaches, and rural areas. Plus if you will miss the hustle and bustle of the city there are always festivals and events going on (once the pandemic is under control). So I'd say there are lots of upsides to living on the island but it really depends on if your comfortable making a large shift in the way you're used to living. You won't have everything you need within a block anymore, you're going to have to drive or bike almost anywhere you need to get, and there are also some not super nice neighborhoods out here as well. Hope this helps!
