Having lived in both New York and Singapore, I can’t say I’d recommend Singapore to anyone who loves NY for the aspects you mention (but there are other reasons to love SG!). I think the scale of opportunities for recreation, arts, and really just a diversity of experience is vastly different. In APAC, I’d suggest Hong Kong (where I’ve also lived) instead, though that is even more like London than NY.
