2015 Volkswagen GTI vs. 2013 Ford Focus ST
Another win to the GTI
The seats in that ST are shocking!!! 
This is the subjective part I think as there are plenty who love the ST out there but I really struggle to see in looks externally and internally how it is ever preferred to the GTI? and even on road it seems something you spend most of time taming rather than enjoying.
That interior is garish, awful! and would genuinely just annoy me having to look at it each day with it's awkward over accentuated shapes - But that is me I suppose as I prefer minimalist which has an obvious feel of class and quality.
