To me the post is really not making the case at all that OCaml's object system is "best", as suggested in the HN headline. Really the only comparison to any other system is contrasting row polymorphism to duck typing. Like another user I was actually expecting this to be about CLOS based on the title. It'd still be a hard claim to make given some of the warts CLOS has, but at least it's a claim that people will often genuinely make. (This also seems to be the fourth time the same post was submitted by the same user, with increasingly clickbaity headlines.)
