Doha VS Dubai.....
It all depends if you are a family man or not. If yes, then Doha is much better! If you like to have millions of activities, nightclubs and restaurants....then go to Dubai!
Doha is very small and quit, everything so far is orientated to families with lots of activities, spectatcles, childrens playgrounds and parks, good schools etc.....Its very safe as well, alcohol usage is limited and criminality is almost inexistant. No prostitution visible.....
Dubai is more a world city with all the positive and negative aspects of it.....as I said, it all depends what you are looking for.
I have lived in both and I have to say that I like Doha a lot. Its not as hectic as Dubai, the life style is very easy going, desert driving is nice, the cornishe is beautifull!
I do not spend half the amount of money that I used to spend in Dubai, mainly because the temptations are not as big here.....
Doha is changing rapidly though and overhere we are all hoping that they wont make the same listake as Abu Dhabi and that is to try to copy Dubai!
EK vs QR.......thats another question although I am confident that QR is moving in the right direction.....
