I don’t remember that being the case for at least half a decade, while my 2019 Thinkpad still has such an awful trackpad.
I would agree that trackpads are good enough on Linux, but not great like on a MacBook. Things like gesture support are unquestionably better on macOS.
Certainly PC trackpads are inconsistent, which is unfortunate. Ideally you should try the trackpad on a laptop in person before you buy it (although if it feels great, and cursor movement sucks under Windows, might be safe to assume that's fixable in Linux).
Interestingly, while I do appreciate some of the gestures on Macs (I don't use many of them), I'd trade that for having physical left/right buttons. I can even play casual games on my Dell laptop without plugging in an external mouse because the experience left/right clicking is so much more reliable.
I think you should leave this one out, because it's at best subjective. I've had a much better experience with trackpads on Linux than I have had on any Mac I've used, thanks to the synaptics driver. Far more customizable as well. Additionally, until pretty recently you'd be stuck with the nasty hinge-based touch pad on Mac laptops which required quite a bit of force to push, and tap-to-click was very much an afterthought.
