Vantaggi
The scripted lessons are from an excellent standards based program. Teaching small groups is intimate and is always wonderful (if you really want to teach). The company has access to $$$ so they can get supplies to you, if you can afford to purchase them yourself and get reimbursed that is faster.
Svantaggi
This is based on federal $$$ so there are tons of paperwork. You are "officially working" whatever hours you are actually in front of students, however there is prep for every lesson, monthly reports, assessments to gather, and other paperwork that you are not paid for. It is all included in the salary which assumes that you know there is always paperwork, If you are not organized, you will not make it. Your immediate experience is a function of how efficient, honest, and friendly your supervisor is. Mine is great.
