Things to be considered are:
environment (pollution etc)
job prospects
human rights (equality etc)
healthcare (cost, quality)
education (cost, quality)
renting/buying property
when you consider all the things you can not make one choice but ultimately its Pakistan for me . . . Jahan bhi chalay ja'ain Pehchan tau Pakistan he hay
I'm reading good things about Malaysia. So that's my vote. I would ideally like people to say Dubai because I want to emigrate there, but from what I can make out, you need to have a good job (sponsor) or things might not turn out to how you imagined.
I think Pakistan will be near top or top when the infrastructure is improved, as well as the political climate.
