To the extent that one can speak of advantages and/or disadvantages at all, I would rather go into what makes induction unique and where induction is less appropriate or applicable.

Brings the test person into deep somnambulism in less than 6 minutes in some cases

Good introduction to the Esdaile state
Works in over 80% of cases
Good induction for audio recordings
Can be used in online sessions (slightly adapted)
Built-in tests to check suggestibility (“hynosis depth”)
Structured
Disadvantages
Can cause difficulties with:
People who have a strong need for control
Subjects who have a lot to do with numbers in their job (bankers, business people, tax consultants…)
