This is a bit difficult to answer as it can depend on personal circumstances - What itches me might not necessarily itch you. So remember that what I say might be interpreted as total rubbish by someone else. I am not trying to put you off Mauritius, but the move will differ from that of UK to FR, hence my suggestion that you go for a year, or so, to see how you get on.
As a bit of background, I was born in MU to non-mauritian parents and grew up there before moving to the UK, and I have lived in Paris for 2 years (and eventually hated it). I wouldn't personally live and work in Mauritius at my age, 32, though I could consider it as a retirement destination when the time came, and as a holiday destination, is second to none)
These are my main gripes:
- Despite MU's multicultural credentials, the colour of your skin still
counts and significant differences between ethnic & religious groups remain - across all social divides. This seeps into important areas such as employment, politics & government services.
- Though improving, it is not as advanced in it's development (services/entertainment) as Europe, so you might find that, due to its size, you get bored real quick after you have "seen & done it all".
- Graft, plenty of it.
- You are a foreigner, so you will be perceived & treated as someone with 'unlimited financial resources'.
Edited to add:
You can follow what goes on in the country, by reading two of the main newspapers, in mainly French, at:
