125th question

Hello, I plan to buy a 125er. In the narrow selection there are a Vespa GTS, Kawasaki Ninja 125er and a Hyosung GV 125 S Aquila. First of all the question arises me because of the manual transmission. I drove a 50er automatic and is really pleasant. Actually I do not want to drive a scooter. I live in Berlin where there is a lot of traffic and ask myself the question how it drives in a big city with a switch. Do you get used to it? or is that d Is it too annoying? Generally, someone has experiences with a Kawasaki or Hyosung? I am happy about your opinions.
