Now I'm going to refer to two quite different aircraft, so that might disqualify me, given all that has been said thus far. In 1970, I was short-toured from the RAF's really rather underpowered Belfast to go to the US on exchange on the Lockheed C-141A, a very different beast. On my first takeoff from Travis AFB, as those P&W engines bit and I was pinned to the back of my seat, had you asked me if thrust was transformative, I would have been in no doubt whatsoever as to my answer!
