Let me give you a skewed perspective on this Doha Vs Dubai debate..though you can search around and find out...

Salaries and expenses may be similar..

Add 3 Hours every day in traffic wasted on Dubai roads to Half an hour in Doha...

In dubai you would "see" loads of partying oppurtunities and fantastic night life (the operative word is see) but your employer will load you with enough work that you would only have a thursday (now friday dubai has changed to friday/Saturday weekends like Doha )night to get wild..If you stretched yourself and tried it regularly ..workplace and health will take a quick toll on you.....

In Doha you would "have" loads of time to party...but you wont "see" much oppurtunities other than a couple of jaded "lets get on with it" type, "the only excitment I get from these parties is the one that I generate myself" type gatherings...Loads of forum discussions are definite pointers...

If you are coming to the gulf with a family in tow, and your family prefers quite night outs and get togethers...You would prefer to hear your children converse in the car than loud music..Your destination shall be Doha...

If you are single..and would love to party and have fun...Take a plane to Dubai..Money and savings are not everything if you are young and single..(and ready to mingle)..

So is Doha about to become another Dubai...unlikely..I guess they are content with the "ideal for family" tag.
