So far, all indications are that the fixed header size means nothing,
in terms of speed, but the *extension* headers are a significant
complication and source of problems.
Some of the other claims (e.g. more secure because IPsec is always
available) are simply wrong - there is plenty of IPv6 equipment that
doesn't offer IPsec.
