I prefer the touchpad on my Surface Book 2 to the one on my Macbook Pro (2019). The one on my Macbook is comically huge, and I also am not in love with the feel/click noise compared to the Surface Book. YMMV.
I have both an XPS 13 Developer Edition from 2018 and two MacBooks from 2019. The touchpads on both 2019s are not good. They both have difficulty inertial scrolling and the touch rejection is far too sensitive.
Coming from lifelong Linux-land it's actually comical reflecting on how poor these things operate in day to day. The most prominent issue for me is how poorly they operate with my USB-type C dock I use for multi-monitor.
No idea, it's very new so the driver side is probably flaky. This being said Lenovo is shipping it on Thinkpads and the likes, so Linux support shouldn't too far fetched.
I have a dell XPS and it's a dream. Probably the closest thing to a good trackpad. That being said, Apples keyboards, even on the MBP are below par. They don't feel like they're supposed to be put through their paces. At work they make us use Macs and iMacs and to be honest, I damn near threw the wireless keyboard in the trash but Apple will win the screen wars till Jesus comes back though.
I'm probably not the person to ask, I only use the touchpad as a last resort.
(Honestly I never even noticed that the apple touchpad was better than any other touchpad, but I understand that touchpad users will notice things I didn't.)
