Have you tried adding a link from your page on the topic to the one that ranks highest? Not only might it be useful for the user but also the fact it's ranking first makes it an authority. Can't do you any harm and would potentially also be very useful for your viewers as they get several opinions.
Obviously there is an argument that you are sending traffic to a competitor but firstly, they will probably find it anyway if it's ranking first and secondly, doing this actually means your site potentially offers more options.
