On most modern cars ABS also has a function of brake proportioning and just turning ABS off can really ruin your day. Even my 95 M3 when it lost ABS was not driveable if you were trying to brake anywhere near threshold.

i know how you feel...after years of only driving race cars on track, I only got into tracking cars with ABS in last 4-5 years and it took a bit to get my head round it. I was trying to brake up to the point the ABs kicked in, but not past it,

After driving a real GT3 - i.e. A race BMW Z4. I got the hang of it. The team told me to just stand on the brakes as hard as possible and stay on them, instead of bleeding off like you would normally think to do. Let the ABS work, and drive right into the corner on the brakes/ABS

At the risk of opening a can of worms, I think that is also the way to drive modern Porsche GT cars fast. If you try and avoid ABS kicking in, you won't be going fast enough. Absoluteiy stand on them at the last possible moment and drive in on the ABS. The skill is in judging how late you can do that, as ABs doesn't change physics with reference to car getting round the corner.

The oposite of finesse, and not saying I wouldn't prefer ABS off, but if you want to go fast, that's the way to do it, IMO.
