You cannot compare living in AUH or DXB to DOH........the winner is UAE
Qatar is strict, overpriced and day to day items you might be used to from western world not widely available. Very slow lifestyle (might be good for some
Medical services are 3 categories below what you can expect in UAE.
UAE (AUH, DXB) is on the other hand crowded with people, however higher competition brings the best out of them. UAE services are way more professional.
Depends if you like to live in the city (stay AUH) or village (go to DOH)
Qatar likes to control your whereabouts. Most of the time you have to present yourself with your ID (resident) or passport (visitor) if you go to bars, so that they know who visited.
if you need to leave the country you have to apply for exit permit?
Depends what kind of job you get...however there is also lots of control on who can visit you and what time they have to leave
