I and many others now rely on the TouchBar daily, for everything from word suggestions too quick access to tools in pro apps.
Adding a real escape key made the TouchBar so much better for me. I don't love it by any stretch—and probably not so much because of the implementation but just before I simply I don't use my laptop as a laptop much—but the number of people I know who can touch type and incorporate the function keys in any special capacity into their touch typing is tiny. I suspect that number is even smaller than the number of people who use the TouchBar.
Heck, even looking at my everyday use mechanical keyboard versus a standalone Apple keyboard versus my laptop, it's not like the function keys are even put in a standardized place across layouts. To me, the TouchBar has just become a thing to complain about for the sake of complaining.
As noted before, the "soft" escape key was really the biggest issue in the first generation models. Once that was solved, I have no gripes. Separating TouchID was also a plus.I don't make heavy use of it but volume and brightness sliders are nicer than their function key equivalents and I really, really like being able to customize it. Siri is gone and replaced with Lock Screen.
