I'm using both the integrated touchpad of my Lenovo Yoga 2 Pro (produced in 2014) and Apple Magic Trackpad 2. The former with xf86-input-synaptics driver, the latter with libinput. My partner has a MacBook Pro which I sometimes lend to test some stuff on macOS. Overall my touchpads on GNU/Linux feel somewhat better; macOS however wins when it comes to application support and integration. I've tried Windows once on my Yoga and it was completely unbearable.
IMO the main thing GNU/Linux needs in this regard aren't the drivers. libinput will get there eventually (it improved a lot over past few years; initially it was pretty much just as unusable as Windows). The main thing that's dramatically needed is application support. You get an absolutely awful touchpad experience with Firefox on X11 until you set MOZ_USE_XINPUT2=1 environment variable, for instance. However, if you enable it, there's a bug somewhere that's triggered by KWin[0] that sometimes makes scrolling unbearable until you refocus the window. I don't even have to mention missing out-of-the-box touchpad gestures support and the fact that macOS implements them smoothly (say, the transition progresses exactly as you move your fingers), while all of the solutions I've seen on GNU/Linux work as simple triggers.
Let's back it up with some data. I've never seen mouseaccuracy.com in my life before, fun stuff. Tried it with the same settings as the author ("hard", "small"; for 30 seconds):
Yoga 2 Pro touchpad on GNU/Linux (synaptics): "TOTAL SCORE: 345; TARGET EFFICIENCY: 69%; CLICK ACCURACY: 96%"
Apple Magic Trackpad 2 on GNU/Linux (libinput): "TOTAL SCORE: 299; TARGET EFFICIENCY: 63%; CLICK ACCURACY: 87%"
MacBook Pro 13 Mid-2012 touchpad on macOS: "TOTAL SCORE: 286; TARGET EFFICIENCY: 58%; CLICK ACCURACY: 93%"
Apple Magic Trackpad 2 on macOS: "TOTAL SCORE: 262; TARGET EFFICIENCY: 56%; CLICK ACCURACY: 82%"
It was definitely harder to do those fast clicks on the Magic Trackpad, because it only emulates a clickpad, while all the other touchpads can be physically clicked (this is a feature that actually made me buy the Magic Trackpad as it makes it exceptionally quiet, but it doesn't really help with accuracy and agility). When it comes to "personal feeling" during the game, the Yoga touchpad handled by synaptics driver definitely felt the best, while all the other runs felt kinda similar (libinput won with macOS in numbers, but I didn't really "feel" it).
