I don't know about Thinkpads, but I've owned over a dozen Dell laptops. Their touchpads have been between Terrible to OK on Linux. Until my most recent Dell, the Precision 5510 (the business version of XPS 15). Finally almost as good as a Mac, but very slightly not as good on palm rejection. I stopped buying Macs due to the ESC key, the butterfly keyboard, the touch bar, and the removal of USB-A ports, so I'm very happy to have the Precision 55xx options. Strangely enough, my only other laptop whose trackpad as almost as good as the Mac is my cheapo Chromebook.
