The surface book touchpad is every bit as good as anything Apple has to offer. I owned 5 different macbook pro/airs prior to making the switch when the touchbar MBP came out.
Comparing insert other hardware manufacturer and laying it on Microsoft isn't really fair... they have no control over what the hardware mfg's put in their laptops. And they can only fix so much in software when there are literally thousands of combinations on the market at any given time.
The surface book touchpad hardware itself might be as good as the trackpad in Macbook's but the software support in windows is not even close. Almost everything but UWP apps and some other first party windows apps have jittery scrolling even with the best trackpad hardware, which is not the case with mac apps.
Either you've never used a surfacebook, or you've got faulty hardware, because that is 100% false. I spend exactly 0 seconds of my day in UWP apps.
There is absolutely 0 issues with jittery scrolling, and out of the 10 or so people I know with SBPs, not a single one has ever mentioned that as an issue. And given that everyone in my group that is on an SBP was previously on an MBP, those cries would be loud and frequent.
