Licensing does not necessarily mean "quality work". I have witnessed work by so-called reputable EC's that was some of the worst workmanship and code non-compliance that can be imagined. In many, many areas the large contractor's work is not even inspected as the inspector relies on the EC's size and assumes the work is O.K.
So, a license is not a substitute for knowledge and ability as from reading postings I believe several forum posters would agree.
