My choice is Activa, but if you can't wait, you can go for Access or Wego.
Personally I believe as far as the their CC are identical, it does not make more difference, I would choose the one that looks nice/attractive and beautiful to me.
When I purchased my bike, I was confused between pulsar and apache, I then choose Apache because it was new and there were quite a few apache in my city, It has been five years and I have never regrated the decision, and neither i would have gone wrong with pulsar. Almost all the competing bikes/scooters are similar, just choose the one that you likes most. These are just my thoughts though.
