Yeah, personal preference. I will say I tried a guys PB stout early this year and it wasn't AS bad as I thought it would be. It was a chocolatey stout, so it had a sort of Reeses Cup thing. Honestly I drank the pint out of politeness. The first couple sips were enough. OTOH not everything I brew is everybody's cup o tea.
EDIT - I'm a PB lover too. Just didn't care for it in the beer.
