A few minutes during a test drive is not enough to understand the pros and cons of B and D.
Once you have the car, I suggest that you try again over an extended period.
That's what my wife and I did when we got our Golf GTE nearly four years ago.
I enjoyed learning the technique of using B properly and have continued to use it exclusively ever since. A little adjustment was needed when changing to the November 2020 ID3 but 2.1 upgrade takes me back to virtually the GTE technique.
My wife has stuck with D after her experiments. That means our brakes do not rust like they would if I was the only driver.
It's a very relaxing car to drive either way and I doubt that you could measure any difference in economy.
