I also love the tax credit for the CPF contribution as I essectially get a portion of my income tax free so long as I save it, plus it bears interest at a competitive rate goven the security of the CPF.)
Even people from less developed nations (i.e. Malaysia, Philippines) feel the same way (from those I have talked to.)
Even if you do decide to switch it is much easier to resume UK citizenship (as you would have renounced to become a citizen of a Commonwealth country.)
As for friends-I have met people who have work passes/PR that are from Germany, UK, USA, Canada, France, Australia, so I am still 'reminded' of home and we share our experiences as such, though it can't really be replaced.
