To ERG or Not to ERG?

I’m in the 2nd week of the Road Racing Interval plan. Are there compelling reasons to use, or not to use, ERG mode when doing the weekday interval workouts? In short, is one mode better than the other?

Here is a great thread on that! For the most part, the FasCat coaches advise against using erg.
