It's a matter of opinion.  UML thinks that <| points is pointing in the "right" direction (towards the more general object).  However, a lot of people think about inheritance as methods flowing from/provided by the super thing to the sub thing.  That perspective is more in alignment with -> 

At this stage, choice of a symbol seems to be most about what will cause the lesser about of opposition based solely upon the symbol choice.   Some people seem top really hate <|.  If there a reasonable alternatives that don't generate the same sort of negative response then it is worth considering them.
