I would have agreed with you many years ago, and even tho now there are still a lot of laptops that have bad trackpads... I honestly have 0 issues switching between a MacBook trackpad, and the one on my ThinkPad.
Granted I'm still scared to run Linux on a laptop as I don't believe I will get the same battery life out of it as I do with Windows. So I've never tested the trackpad under Linux. On Windows it's great.
