What’s your usecase for it? My work laptop has one and I use it to change the brightness of my screen and to lock it. That’s it. I really miss the physical escape key, especially when using vim...
You may already know this, but you can remap your Caps Lock to escape if you don't use it (System Preferences -> Keyboard -> Modifier Keys). It keeps you on home row too, which is nice for vim.

I have a physical ESC key, so I don't have a problem with the touchbar.
