2,0 tfsi or 3,2

tach, I’m on it and I’m about to order a SB, first the question was whether it should be a tfsi or a tdi. the question I answered myself with the fun factor and the tfsi was clear. then the question was still whether dsg or “normal”. for this reason my dealer gave me a test car via we, nn a3 8p, 3,2 with dsg…… almost he wouldn’t have got it again, such a cool car… but now I have a real problem… I can’t decide anymore. n. nn tfsi I can’t test it either, because not available. is the difference in performance big??? noticeable??? what about the consumption, is the really 2-3l?? for tips, I’m grateful for some experience.
