The Scotland captain acknowledges that links are often drawn due to a similar attacking playing style out from defence.
Yet the constant questioning of who is the better player, based on specific performances, is not something that Robertson particularly cares for.
"I've spoken to KT about it before," Robertson said on the Lockdown Tactics podcast.
"Me and him are probably sick to death of everyone comparing us. One good performance from each of us and it's one of us is better than the other.
"It's just two players playing at a good level.
"It gets a bit tough when everyone in Scotland starts comparing you. Steve Clarke will have his own ideas and whatever he does it's for the best of the team. Whether that's playing one of us or two of us, we both have to deal with that."
