Depends on your goals and definition of good quality of life. I think there is no best place for a avarage developer. Every life is so unique, skills are so leveled per de developer and matching economics and jobs on these are very specific.
As a dutch man, i can tell you just my experience as a software developer that here in the big cities are enough places to get jobs. Daily mails from recruiters sesrching for new candidates to be places at all sorts of companies. Living here matched about the avarage income to live in a small home with wife and kid.
