I think a big part of it is that Boruto is the only one who can access this tool. It's not like a genetic advantage, it's an unfair advantage because no one else gets the chance to use it while he can. Comparing it to Puppets, swords and other ninja tools is silly because if a shinobi wanted to they could use those tools, but in this case Boruto is the only one who can use it (Correct me if I'm wrong) so it gives him an unfair advantage over any other combatant only because they can't use the tool even if they wanted to.
