Imagine how I felt when I was unfortunate enough to own an Omega and a Focus at the same time, probably 2 cars at the opposite extremes when it comes to servo assistance. At the first junction, I had to consciously remember which car I was in. Beyond that, I was pretty much tuned in to them - well, as much as you could ever get used to Focus brakes.
I think the Focus was over assisted, ok no effort required to rub you nose on the screen, but no feel/feedback through the brakes (and massive fade after a couple of big stops, but thats not relevant in this conversation). This lack of feel meant under even moderate braking, I found the car in full lockup conditions (no ABS).
The Omega may be considered under assisted, but the feedback is very good (and in good condition, can take a few big stops before fading, but not relevant here). So although more foot effort needed, you can, from very high speed, be teetering on the maximum the tyres have to give.
I guess some prefer a compromise in between.
On a slightly different slant, but related, I find TC pads have no bite on the first application of a journey, which gives the same feeling. Subsequent applications seem OK. EBC pads give the same, worse on the track pads, like Red Stuff, that need a fair amount of heat to get them working. So pads do also have an impact, hence I tend to recommend, for most, TC pads.
