Depends on what you need. I really hate 16:9 aspect ratio on laptops so the XPS and Surface Laptop 3 are the only ones I considered. The HP and Lenovo have really bad touchpads so if you make use of the touchpad in Windows a lot then that may drive you nuts. The new XPS 2-in-1 has the maglev keyboard which is a love/hate keyboard. I love it. A lot of people hate it. The XPS 13 9300 didn't go with the maglev keyboard so it either isn't popular or its just needed in the 2-in-1 form factor. The XPS only has USB-C ports.
I mean you could write page upon page on how these are different but it just comes down to your preferences and requirements.
If you just want to write your notes on it. Maybe look at a 2nd gen surface laptop (I know it is only 13 inch) but it has a really nice keyboard. If you want to game on it too, the Asus Vivobook K571GT-EB76 is a Bang for your buck at Amazon right now. If you only want battery life the DEll Latitude 14 7400 has with more than 13 hours and is the best on the market (an i5 version with 16gb is under $1000)
