Real escape and full row of real F- keys. Just push the Touchbar above it, so we can power it down and ignore it (or run cute screensavers on it while plugged in).
The whole concept makes no sense. "Don't look at the computer's screen when you work, look down at your keyboard instead!" It is like an anti-touch typing gimmick, the tagline should be "become a worse typelist today!"
If you want to stay sane with touch bar, buy one of those keyboard covers for non-touchbar models with ESC/Fn keys, pad the Fn keys with some pieces of rubber. Then you can have have some poor man's tactile feedback. The very latest keyboard is improvement both in sound and feel, latest CPUs are very fast, just the touchbar kills the overall impression.
