As for Serbia, I’d give it a solid 4.

Negative sides: The life standard is decreasing. Whole country is being centralized around Belgrade. When you get sick you need to be manager of your own sickness or doctors won’t know what to do. There are more jobs but in general salaries are smaller. Middle class gone.

Positive sides: There are no wars, sanctions and flammable, fascistoid rhetoric as much as during 90’s. People are still hospitable. More opportunities (funding) if you seek job to open your start up job.
