I've had decent experiences with most Dell, Lenovo and Asus laptops but I also do not use some features like fingerprint readers and even though it seems to work on my Asus I dont really use the touch screen. While you did not ask about printers I have had good experiences with Brother laserjet printers and CUPS over wifi with my Linux laptops.
The Lenovo's I used had a weird firmware issue unrelated to Linux. At times I would have to hold down the power button for 20 seconds and then push it again. It would get into some weird power save loop. I assume they must have fixed that by now.
Not so much related to Linux but I had enough trouble with HP laptops hardware wise that I just avoid them.
