Yeah - it's hard to know if that will still be the case in 10 years time - so much can change so quickly - but here and now on a purely objective view I think you are right. The main downside of Singapore for me is the climate, but apart from that it offers many of the upsides of Hong Kong (low taxes, safety, good public transport, great airport) without some of the worst downsides (rubbish housing, increasing mainland integration, abysmal political system).
