Having a Mercosur passport (Argentina) and EU passport (Spanish) I think I have a pretty sweet deal - Spanish passport gets me visa free to most of the countries in the world, and the Argentinian passport gets me to Russia visa-free (hi Putin!). And then on top of that I can live in any EU country and also live and work in any (or most I think) Mercosur countries without having to worry too much about work visas, etc. When I see the kind of hoops that some of my fellow countrypeople need to go through just to find work abroad (i.e. come to the EU) I really really appreciate that my mam was intelligent enough to tell my 15 year old self to go get the citizenship when we could.
