[General] Is a vibroknife (with vibrating blade) worth the fuss? Does it cut better, faster, or deeper?

A vibro-knife works using the same mechanics as a chain saw. Instead of having to press down with immense strength, the knife cuts 'for you' through a powered high-frequency vibration. 

In effect, this makes the blade 'sharper' in that it requires less effort from the user to cut through stronger/more dense materials.
