As Rhyso said lots of cars are 'better' than a MK4 Golf. It depends what YOU want from the car.
A ford focus of the same year will handle better standard over standard. Loads of cars are faster.
For normal road driving the mk4 is fine, its no track car in standard form but how fast are you driving on the road?
If you have to ask 'should I keep it' then its obviously the wrong car for you and I say sell it and buy a car you want / does what you want it to.
