What??? Harder to raise brand awareness for something that is different??
As a marketing advisor, you certainly make a good pilot, Psycho...
It's all about "point of difference" old boy. Why would someone change brand for something that is ostensibly the same. Where is the incentive. It's marketing 101 - provide an offering with a point(s) of difference to be able to drag the punter away form their usual spending habits and choice of brand. "Subtle" does not break deep seated buying patterns.
