I think Dougie is more handsome/attractive whereas Mark is 'hotter' if that makes any sense whatsoever. Someone who I find hot is more or less someone who I'd rather .. well..
do.. than someone I'd want to spend my life with. Dougie's more someone that you'd rather bring home to mum.
Maybe I'm giving this too much thought..

But yeah, none are really my type in the looks or personality department.
