Rarely, and for specific reasons.
LEGITIMATE REASONS
A partner, regulator or payment processor requires organisation or extended validation, stated in writing You need a financial warranty for contractual reasons You need a wildcard or multi-domain certificate on terms AutoSSL does not provide Your certificate must be issued by a specific authority for compliance
NOT REASONS
Encryption strength, which is identical The padlock, which looks the same Search ranking, which is unaffected Professionalism, since visitors cannot tell A dedicated IP, which modern SSL does not require
BEFORE BUYING
Ask whoever set the requirement to state it precisely. Requirements are frequently less specific than they first appear, and "SSL certificate" usually means any valid certificate.
WHAT YOU TAKE ON
A purchased certificate does not renew itself. You must remember, generate a new request, obtain and install it, every year. A forgotten renewal produces a browser warning on every visit.
THE RECOMMENDATION
Use AutoSSL unless you have a written requirement that it cannot satisfy.
