Direct-Drive VS. Bowden

Should you convert your Ender 3 to direct-drive or stick with a Bowden system?
Which extruder system is best and does it really matter?
What advantages and disadvantages do the two systems offer?
In today's episode, I compare them side by side: No personal opinion but only objective and quantitative tests.
I look at printhead weight, print speed and ringing (with and without Klipper input shaping), printer resonance, max acceleration, extrusion efficiency, retraction quality, filament compatibility etc.
