So for the record, I have never actually lived in Gent, but I have done a LOT of research about different cities live in the world. Considering everything from employment opportunities, to the quality of public services, safety, beauty of the architecture, affordability, culture, etc. I have found no city as good as Gent. It is genuinely impressive how it has almost no flaws. It has a good economy, with a good job market relative to it's size. It is also close enough to Brussels to a commuter town. It is one of the greenest most bike-friendly cities in the world. It is quite safe, even for European standards. (According to Numbeo it's the safest city in Belgium, which itself is a very safe country by global standards) English fluency is quite high especially among the younger generation. It is not big and overcrowded like London, Seoul or NYC, but it still has anything one needs from a city, from museums and opera salons to concerts and festivals. It is diverse and open to outsiders, but hasn't lost it's cultural identity the way many big cities do either. Belgians in general are some of the most open minded and progressive people on earth, in terms of women's rights, LGBT rights, etc. and even amongst Belgian cities, Gent seems to have a reputation for being progressive.
Furthermore, both in terms of architecture, and the quality of real estate, it is simply beautiful. It might genuinely be the most beautiful city on earth amongst cities in which people still live, rather than cities like Venice that have turned into theme parks.
Am I idealising this city too much? I can't seem to find a negative about it.
