I have bought/used a lot of high end ($2000+) windows notebooks: acer, asus, MSI. The trackpads all suck. Seriously, it is insane - macs had a working mouse in 1984!
You bought all the junk. Thinkpads and expensive Dells and HPs are good. So is the surface book. The brands you listed are good at making low quality laptops. Their high end sucks. Lenovo's high end is top-notch and their low end is not as good as Acer's for example.
