What scooter?

I know the topics of this kind have already been discussed 100 times! I also used the search function. The question is: Which scooter should I buy? I am soon finished with my M driver’s license and would like to buy a scooter should not be a cheap scooter. So far only 1.73m tall. Had to drive with it every day about 20 km. A little tune I would like already so that it runs about 60-65 kmh. Optics is not the most important .. much more important is quality. These 3 scooters come into question so far : Aprillia Sr 50 Street Piaggio NRG DT Gilera Runner 50 SP Which of these 3 scooters is best in quality? Which scooter would still be in question? Thanks already for the answers
