DSG manually switch bad for overtaking maneuvers?

Hi. I want to buy a Seat Leon. I’m thinking if it should be automatic. So I did some test drives. I want to have 150 Ps and a sporty driving should be possible. I have the feeling that it is slow during the overtaking process. Why: When I see a gap in the overtaking lane I give gas. The automatic transmission switches down and the car accelerates. But switching down the transmission takes a moment. Therefore, during the test drive I have f The car had two modes: D for automatics and S for manuals. I noticed, however, that I do not have to switch to S for pressing the switch paddles. My question now: can I drive in this way with an automatic transmission or is this harmful to the gearbox? Do you see this also so that this mode is better accelerated. t as the use of pure automatic or do I do something wrong? Thank you Lg.
