OCI isn't a substitute for dual citizenship and doesn't offer all the benefits other citizens of India have. However, with this, you can get life long visa free entry to India and exemption from having to report your stay and movements to police when you're in the country.
One major downside is that there are limitations to who is eligible. Not only must you fulfil the family eligibility described above, you can be barred from the scheme if you or a family member live or have ever lived in Pakistan or Bangladesh.
