IMO not close (I spend the majority of the day on my work macbook). It's especially apparent when scrolling or moving the pointer small amounts, and especially near the edges of the trackpad, where you need to make bigger movements for it to work.

Your mileage may vary as people have different sized fingers and such.

It's a far cry even from my old Google Pixelbook, which is a (distant) second best touchpad I've used.

Besides the actual hardware, I think the biggest problem is the software implementation of trackpads in Linux (at least in libinput/Wayland). Even running Linux on my Macbook, the trackpad experience is vastly inferior to macOS.

I don't care too much about gestures, but mostly about stable palm rejection and proper acceleration curves. The current implementations sadly provide neither.

very similar. One would think they're on a macbook when using this laptop. I have it set to use "area" for left/right click and it works better than my older macbookpro where the trackpad had lost some of its responsiveness at some point.
