You can't consider it a Hot Hatch... they were by definition a Hot version of the normal Mum and Dad Hatch... ie Golf GTI, Golf R, Focus XR5, Focus RS etc... The Scirocco is a Coupe body... it does not share its bodywork with any mundane Mum and Dad model... the fact that it can carry 4 adults in reasonable comfort is testament to efficient packaging and overall size... nothing more.
You can see that when look at a Golf R next to a Scirocco.. as below.

As for competitors... well you could if you wanted compare the Roc to an Aston DB9 as they are both Sports Coupes but the reality is you need to look at the Class of the car not just the style description... and as such the Megane 250 is the most obvious competitor...
Everyone will have there own take on it all... at the end of the day it doesn't matter..
I am more than happy with my Roc.. although if someone wants to swap their DB9 I would consider it...:)
