I've used both (albeit the Mac was a 2010 Macbook Pro so they may have changed - the Dell is a 2019 XPS13 and is my current travel laptop) and I'd rate them roughly on par. The Macbook had slightly better accidental touch rejection iirc (eg. if you brush the touchpad while reaching for the keys to type) and slightly nicer build quality. The XPS is really nice though.
