I have never driven a ka. Some focuses but the only one that stood out was a 2001 st170. At the time I thought that was the only real hatch to better the GTi6.
Only driven the 1.6 ka and that wasn't standard so don't know, but the KA fiesta puma are the same floor pan and suspension (ish) so wondered how they would compare.
The ST was quite modified suspension from the standard from what I remember. So not comparable to a 'normal' focus.
